Polytechniek emphasizes the transition to natural refrigerants. Is a natural refrigerant an opportunity or a threat?
After the ban on R22, Due to the depletion of the ozone layer, the next round is now underway in Europe, the transition to refrigerants with less greenhouse effect. This is referred to in English as Global Warming Potential (GWP). The refrigerant R507 or R404a, widely used after 2000, has a GWP of almost 4000, which means that 1 kg of this stuff has just as much greenhouse effect as 4000 kg of CO2.

With a car that emits 100 g / km you could drive 40,000 km for the same effect. The high GWP refrigerants are banned worldwide because refrigerant leaks into the atmosphere through leakage. As of 1 January 2022, in a number of cases no new refrigerant with GWP . may be allowed> 150 more to be installed new. Even R134a is then eliminated. For existing installations, topping up with refrigerant GWP> 2500 banned as of January 1, 2020.

Polytechniek BV has had an excellent reputation in the field of cooling technology since 1980, especially in the agricultural sector. We supply various cooling installations, the control of which is tailored to the project and with which the installation runs as energy-efficiently as possible. This integration ensures perfect coordination and efficient operation.

The different cooling installations that we build are:

– Air conditioning;
– Separate dx cooling systems;
– Central dx cooling systems with expansion valves;
– Central pump cooling systems;
– Indirect central pump cooling systems (ammonia);
– Central pump cooling systems (ammonia);
– Vacuum cooling;
– Dry cooling.
