High customizationNew air and water cooled liquid chillers, for a diverse globaleconomy, in any industry, in any location and in any climaticcondition.

Hitema understands the increasing energy consump-tion required by industrial processes and that it is direct-ly against the environmental drive to reduce our CO²footprint. Hitema through its extensive research anddevelopment, has developed advanced technologies toprovide a solution to its Customers, whilst still ensuringreliable and cost effective, flexible products, which highefficiency at its core.

The new high efficient generation of screw compressorsand shell and tubes evaporators with dry expansion,increase the efficiency of our systems. Through the useof R134a, and a cooling circuit that includes an econo-mizer, we can reach the right result whilst maintainingthe cost vs efficiency debate.

The use of electronic expansion valves and advancedcontrol systems, allow us to guarantee the highest ener-gy savings. In fact because of the PID control and regu-lation of superheat ensures the efficiency of the refriger-ation circuit is maximised.

Speed control of the condenser fans by inverters, allowthe minimal use of energy no matter what the externalambient. At Hitema we pride ourselves on the full andpartial load efficiency ratings of our systems, maximisingthe highest ESEER or IPLV figures of our products.

Our free cooling system is managed to maximize heatexchange and guarantees heat extraction no matter whatthe external environmental conditions or process load.Our use of modulating free cooling valves, combined withour variable speed fans allows us to reach the best solu-tion in any climatic conditions, from -40ºC winter temper-atures to summer temperatures in excess of 50ºC.

Our experience from thousands of installations aroundthe world in both civil and industrial applications, haveallowed Hitema to develop our technical knowledgebase. Our use of cutting edge technology, has driven ourproduct development to provide a flexible solution toyour needs, and the best way to guarantee to our Clients,that high efficiency can be achieved with reliability.

Every unit needs to be reliable, for this reason Hitema’strack record for reliability of our systems is second tonone. All our units have sophisticated safety systems toguarantee trouble free running and with Free cooling theactual wear on the refrigeration system can be reducedby up to 90%, therefore extending the life of the systemand reducing service and maintenance costs.

• COMPRESSOR

Leading brends of compressors normally utilizedin mono, tandem or trio configuration, featuringhigh efficiency to ensure very competitive COPvalues:- Hermetic reciprocating compressor cooled by liquidrefrigerant on the suction side and protected bythermal overload and overcurrent relays.- Hermetic scroll compressor operating with veryhigh efficiency levels and low electrical power con-sumption.- Semi-hermetic screw compressor equipped as

standard withfour capacitysteps or stepless.The electricmotors feature“PW” start tech-nology and areprotected fromphase sequencecontrol, voltagecontrol overheat-

ing by means of thermistors embedded in the sta-tor winding.Shut-off valves on refrigerant discharge line.

• ECONOMIZER APPLICATION

The economizer is a devicedesigned to improve both cool-ing capacity and efficiency ofthe system, by providing anadditional sub-cooling,achieved with the addition ofan intermediate plate heatexchanger, expansion valveand the cross flow refrigerantcircuits.

Principle of operation The compression in a screw compressor takesplace by means of high speed rotors drawingcoolant into the rotor grooves of the opposingrotor teeth. They transport the volume, that issteadily reduced and so it is compressed, fromsuction pressure to condensing pressure.The pressure at the additional middle connection(economised port) is similar to the intermediatepressure with a two-stage system.As a result of these features, a screw compressorof this design can be combined with an additionalsub-cooling circuit for “two stage ofcompression”. These measures result in increased refrigerationcapacity due to additional sub-cooled liquidentering the evaporator. The power consumptionof the compressor increases only slightly whencompared to the additional cooling performance.

Super low-noise application

Free cooling is…. protecting the environment

Integrated hydronic kit has the main hydraulic components.

• AIR AND AIR/WATER REFRIGERATING EXCHANGER

The new concept of heatexchanger with mechani-cally expanded coppertubes and aluminiumfinned core with swirl pro-file dedicated to conden-sation and to water cool-ing in free-cooling mode.

• COMPRESSOR

Leading brends of compressors normally utilizedin mono, tandem or trio configuration, featuringhigh efficiency to ensure very competitive COPvalues:- Hermetic reciprocating compressor cooled by liquidrefrigerant on the suction side and protected bythermal overload and overcurrent relays.- Hermetic scroll compressor operating with veryhigh efficiency levels and low electrical power con-sumption.- Semi-hermetic screw compressor equipped as

standard withfour capacitysteps or stepless.The electricmotors feature“PW” start tech-nology and areprotected fromphase sequencecontrol, voltagecontrol overheat-

ing by means of thermistors embedded in the sta-tor winding.Shut-off valves on refrigerant discharge line.

• ECONOMIZER APPLICATION

The economizer is a devicedesigned to improve both cool-ing capacity and efficiency ofthe system, by providing anadditional sub-cooling,achieved with the addition ofan intermediate plate heatexchanger, expansion valveand the cross flow refrigerantcircuits.

Principle of operation The compression in a screw compressor takesplace by means of high speed rotors drawingcoolant into the rotor grooves of the opposingrotor teeth. They transport the volume, that issteadily reduced and so it is compressed, fromsuction pressure to condensing pressure.The pressure at the additional middle connection(economised port) is similar to the intermediatepressure with a two-stage system.As a result of these features, a screw compressorof this design can be combined with an additionalsub-cooling circuit for “two stage ofcompression”. These measures result in increased refrigerationcapacity due to additional sub-cooled liquidentering the evaporator. The power consumptionof the compressor increases only slightly whencompared to the additional cooling performance.

Super low-noise application

Free cooling is…. protecting the environment

Integrated hydronic kit has the main hydraulic components.

• AIR AND AIR/WATER REFRIGERATING EXCHANGER

The new concept of heatexchanger with mechani-cally expanded coppertubes and aluminiumfinned core with swirl pro-file dedicated to conden-sation and to water cool-ing in free-cooling mode.

• COMPRESSOR

Leading brends of compressors normally utilizedin mono, tandem or trio configuration, featuringhigh efficiency to ensure very competitive COPvalues:- Hermetic reciprocating compressor cooled by liquidrefrigerant on the suction side and protected bythermal overload and overcurrent relays.- Hermetic scroll compressor operating with veryhigh efficiency levels and low electrical power con-sumption.- Semi-hermetic screw compressor equipped as

standard withfour capacitysteps or stepless.The electricmotors feature“PW” start tech-nology and areprotected fromphase sequencecontrol, voltagecontrol overheat-

ing by means of thermistors embedded in the sta-tor winding.Shut-off valves on refrigerant discharge line.

• ECONOMIZER APPLICATION

The economizer is a devicedesigned to improve both cool-ing capacity and efficiency ofthe system, by providing anadditional sub-cooling,achieved with the addition ofan intermediate plate heatexchanger, expansion valveand the cross flow refrigerantcircuits.

Principle of operation The compression in a screw compressor takesplace by means of high speed rotors drawingcoolant into the rotor grooves of the opposingrotor teeth. They transport the volume, that issteadily reduced and so it is compressed, fromsuction pressure to condensing pressure.The pressure at the additional middle connection(economised port) is similar to the intermediatepressure with a two-stage system.As a result of these features, a screw compressorof this design can be combined with an additionalsub-cooling circuit for “two stage ofcompression”. These measures result in increased refrigerationcapacity due to additional sub-cooled liquidentering the evaporator. The power consumptionof the compressor increases only slightly whencompared to the additional cooling performance.

Super low-noise application

Free cooling is…. protecting the environment

Integrated hydronic kit has the main hydraulic components.

• AIR AND AIR/WATER REFRIGERATING EXCHANGER

The new concept of heatexchanger with mechani-cally expanded coppertubes and aluminiumfinned core with swirl pro-file dedicated to conden-sation and to water cool-ing in free-cooling mode.

• COMPRESSOR

Leading brends of compressors normally utilizedin mono, tandem or trio configuration, featuringhigh efficiency to ensure very competitive COPvalues:- Hermetic reciprocating compressor cooled by liquidrefrigerant on the suction side and protected bythermal overload and overcurrent relays.- Hermetic scroll compressor operating with veryhigh efficiency levels and low electrical power con-sumption.- Semi-hermetic screw compressor equipped as

standard withfour capacitysteps or stepless.The electricmotors feature“PW” start tech-nology and areprotected fromphase sequencecontrol, voltagecontrol overheat-

ing by means of thermistors embedded in the sta-tor winding.Shut-off valves on refrigerant discharge line.

• ECONOMIZER APPLICATION

The economizer is a devicedesigned to improve both cool-ing capacity and efficiency ofthe system, by providing anadditional sub-cooling,achieved with the addition ofan intermediate plate heatexchanger, expansion valveand the cross flow refrigerantcircuits.

Principle of operation The compression in a screw compressor takesplace by means of high speed rotors drawingcoolant into the rotor grooves of the opposingrotor teeth. They transport the volume, that issteadily reduced and so it is compressed, fromsuction pressure to condensing pressure.The pressure at the additional middle connection(economised port) is similar to the intermediatepressure with a two-stage system.As a result of these features, a screw compressorof this design can be combined with an additionalsub-cooling circuit for “two stage ofcompression”. These measures result in increased refrigerationcapacity due to additional sub-cooled liquidentering the evaporator. The power consumptionof the compressor increases only slightly whencompared to the additional cooling performance.

Super low-noise application

Free cooling is…. protecting the environment

Integrated hydronic kit has the main hydraulic components.

• AIR AND AIR/WATER REFRIGERATING EXCHANGER

The new concept of heatexchanger with mechani-cally expanded coppertubes and aluminiumfinned core with swirl pro-file dedicated to conden-sation and to water cool-ing in free-cooling mode.

High customizationNew air and water cooled liquid chillers, for a diverse globaleconomy, in any industry, in any location and in any climaticcondition.

Hitema understands the increasing energy consump-tion required by industrial processes and that it is direct-ly against the environmental drive to reduce our CO²footprint. Hitema through its extensive research anddevelopment, has developed advanced technologies toprovide a solution to its Customers, whilst still ensuringreliable and cost effective, flexible products, which highefficiency at its core.

The new high efficient generation of screw compressorsand shell and tubes evaporators with dry expansion,increase the efficiency of our systems. Through the useof R134a, and a cooling circuit that includes an econo-mizer, we can reach the right result whilst maintainingthe cost vs efficiency debate.

The use of electronic expansion valves and advancedcontrol systems, allow us to guarantee the highest ener-gy savings. In fact because of the PID control and regu-lation of superheat ensures the efficiency of the refriger-ation circuit is maximised.

Speed control of the condenser fans by inverters, allowthe minimal use of energy no matter what the externalambient. At Hitema we pride ourselves on the full andpartial load efficiency ratings of our systems, maximisingthe highest ESEER or IPLV figures of our products.

Our free cooling system is managed to maximize heatexchange and guarantees heat extraction no matter whatthe external environmental conditions or process load.Our use of modulating free cooling valves, combined withour variable speed fans allows us to reach the best solu-tion in any climatic conditions, from -40ºC winter temper-atures to summer temperatures in excess of 50ºC.

Our experience from thousands of installations aroundthe world in both civil and industrial applications, haveallowed Hitema to develop our technical knowledgebase. Our use of cutting edge technology, has driven ourproduct development to provide a flexible solution toyour needs, and the best way to guarantee to our Clients,that high efficiency can be achieved with reliability.
