The base frame is made of heavy gauge electro-welded tubular steel sections throughout, treated with a hardwearing exterior quality protective finish.

STRUCTURE

The sheet steel structure, which features the same passivation treatment and painting schedule as the base frame,is joined to the base by means of an electro-welding

PANELLING

The panelling is made of steel and finished with the same protective treatment.

MODULARITY

Facility to connect several units in parallel, also using modular chillers made by different manufacturers.

SCALED-DOWN DESIGN

The compact size of the units makes for more efficient use of any available space, with reduced footprints minimisingthe installation area required.

REFRIGERANT CIRCUIT MODULARITY

Total cooling capacity is generated by dual compressors rather than relying on a single large size unit. This solutionmakes it possible to divide the total capacity into a series of steps and use reliable and economical standardcomponents, thereby achieving clear manufacturing and functional benefits.

CHILLER COMPRESSOR

The primary chiller compressors utilise tandem configuration, featuring high efficiency compressors to ensure verycompetitive COP values: -

Hermetic reciprocating compressor cooled by liquid refrigerant on the suction side and protected by thermal overloadand overcurrent relays

Hermetic scroll compressor operating with very high efficiency levels and low electrical power consumption

Semi-hermetic screw compressor equipped as standard with four capacity steps.

The electric motors feature part-winding start technology and are protected from overheating by means ofthermistors embedded in the stator winding

DUAL REFRIGERANT CIRCUIT EVAPORATORS

Self-cleaning coaxial type with high turbulence swirl profile.




/5






Direct expansion type with an innovative water/gas design, constructed of heavy gauge copper pipes, immersed inthe storage tank, thermally insulated and crossed by reverse-flows of gas-water that make it possible to achieve thefollowing:

maximum effective heat exchangezero thermal dispersionoperation of the compressor with low compression ratiowith a consequent high efficiency coefficient

AIR-COOLED CONDENSERS

Plate core type cooling condensers with mechanically expanded copper tubes in an aluminium finned core(pre-painted on request) with swirl profile to increase turbulence and hence heat exchange efficiency, complete withsub-cooling function.

REFRIGERANT CIRCUIT

The refrigerant circuits feature a bi-compressor, in tandem configuration with welds executed using silver alloywelding.Refrigerant circuit components: -Mechanical lamination valveFilter-drier - Liquid and moistureindicatorMuffler - Suction separator with relief valveSafety pressure switches on high and low pressuresidesPressure connections for charging and discharging refrigerant fluidClearly visible dual scale pressure gauges

PERFECT CONTROL OF PROCESS FLUID TEMPERATURE

Perfect temperature control is achieved through the use of compressors with continuous capacity control combinedwith a system of hot gas injection to the evaporator. This solution, combined with our 316 AISI stainless steelhydraulic unit, is ideal for cooling of “aggressive” industrial processes in which the temperature differential must bemaintained at ≤ 1°C.

COMPLETE HYDRAULIC CIRCUIT

The flexibility of the hydraulic circuit configuration greatly facilitates the installation and commissioning of Hitemaunits.The hydraulic circuit includes: - Storage tank Relief valveClearly visible pressure gaugeEvaporator protectionflow switchAutomatic air separatorAutomatic filling unit with clearly visible pressure gaugeManual by-pass

SEMI-GRAPHICS USER INTERFACE

Hitema’s microprocessor control systems perform real-time surveillance and prevention strategies. All the mainfunctions of Hitema units are protected against anomalous or potentially harmful operating conditions. Thissafeguard simplifies troubleshooting operations and minimises maintenance times.
