Cooling technology

The PZP company has a long tradition in developing and producing cooling systems. The first systems were developed shortly after the company had been established in 1992. These were single-purpose cooling systems which were used e.g. in footwear and printing industry for cooling operational liquids.

Systems with various cooling performance started to enter the market in reaction to growing demand. This tendency resulted in the development of the MML generation of movable liquid coolers. These were available in the output ranging from 6.5 to 31 kW. Where the cooler was installed permanently - marked SML, the system had cooling output up to 64 kW.

Subsequently, condensation units marked KLS and KLF were developed. In cooperation with ait evaporators, these provide for the operation of cooling and freezing boxes. Cooling systems which are designed to be connected with evaporators of air-conditioning units were marked EL-CH.

Currently, the PZP HEATING a.s. offers MML movable liquid coolers which were gradually improved and equipped with cooling circuit components. These systems contain CopelandScroll spiral compressors and the ecologically suitable R407C refrigerant. MML coolers are still available in standard models with cooling output ranging from 6.5 to 28 kW.

Non-standard requirements, i.e. other requirements for temperatures of cooling liquids, performance of the system, circuit pump performance or increased requirement for transport pressure of air ventilator, can be discussed and systems can be adapted to your needs. Apart from above mentioned possible applications, the MML liquid coolers have been also employed in e.g. plastics production (cooling of injection presses and forms) or cooling of vacuum furnaces.

The PZP HEATING a.s. company can also provide for non-standard single-purpose systems according to your specific requirements. The range of such systems is very vast from very simple coolers up to complex cooling systems.
