PROCESS COOLING

Our industrial process cooling machines are the perfect solution for the countless requirements of production processes.

The choice of a process cooling system is linked to two main aspects, the first being its TCO (Total Cost of Ownership) i.e. efficiency, i.e. electricity consumption, and environmental impact, with both present and future regulatory restrictions.

Our chillers are distinguished not only by their high performance, but also by their low environmental impact due to the use of natural gases such as R290, ammonia and CO2 (they comply with ERP TIER2 regulations)

What are the advantages of using natural refrigerants?

The use of natural gases has several advantages that make these refrigerants a real long-term investment. First of all, they guarantee high energy efficiency with little or no environmental impact. Another absolutely advantageous factor is the lower cost of producing these refrigerants, which will be available without restriction in the next few years, making them a sound investment for the long term.
The advantages at a glance are:

High energy efficiency

Low operating costs

Nessuna restrizione futura

Very low or no GWP (global warming potential)

A long-lasting investment.

AMMONIA CHILLER

W-tech manufactures ammonia chillers (NH3), an extremely efficient, natural refrigerant with a very low environmental impact.

FLOODED VERSION
- Bitzer open screw compressors.
- High efficiency motors.
- Oil separator with coalescing filters.
- Water cooling.
- Liquid separator integrated in the evaporator, reduced size for the same power.
- Semi-welded plate condenser and evaporator.
- Control panel, PLC and electrical system.

<b>COMPACT FLOODED VERSION</b>
Liquid separator integrated in the evaporator, reduced dimensions with the same power.

<b>DRY EXPANSION VERSION</b>
With electronic expansion system.

PROPANE

Our product range also includes air-cooled modular liquid chillers with natural refrigerant R290 and heat pumps.
Propane is a green alternative to the common HFC refrigerants with their high GWP (Global Warming Potential). Among other things, R290 has a very high coefficient of performance, which means that life cycle costs are significantly lower than in systems with conventional chillers.

  • High efficiency.
  • Reciprocating compressor (scroll or screw compressor on request).
  • EcoDesign.
  • For low, medium and high temperature.
  • Various options available.

CUSTOM-DESIGNED MACHINES

W-tech manufactures special machines tailored to the most specific requirements such as for the chemical, pharmaceutical and oil & gas industries.

  • Also in Atex Eex and standard oil & gas execution.
  • For internal and external single or multi-compressor screw or piston.
