About Winsa

Winsa is a production company based in Turkey and founded in 1998, which manufactures and sells PVC systems for windows, doors, and shutters. They have more than 250 dealers and over 500 sales points around Turkey.

What is trigeneration?

Trigeneration is the simultaneous generation of power, heating and cooling using natural gas or biogas as fuel. A trigeneration installation couples a Combined Heat and Power (CHP) engine with an absorption cooling system.

This reduces energy costs by generating own electricity, by using less electricity for cooling, and by applying excess heat usefully.


How the installation works

The CHP unit consists of a gas engine, which runs on natural gas, coupled to an electric generator. This produces 1560 kW of electricity which is then injected into the Winsa’s electric power supply. The heat that is released at the same time is used entirely by the absorption cooling system.

The absorption cooling system functions by consuming heat instead of electricity as its energy source, and uses a thermochemical compressor to produce cooling.

In a low pressure system an absorption fluid (the refrigerant) is evaporated, removing heat from one place and transferring it to another. The energy from the heat source is used to regenerate the absorption solution. This generates 1580 kW of cooling and is used in Winsa’s production process to cool PVC materials after the extrusion machines.

A comprehensive installation

In addition to the trigeneration plant Upgrade Energy set up; Upgrade Energy also installed solar panels on Winsa’s facility roof in 2014. This photovoltaic installation, which transforms the sun’s radiation into useful electricity, generates 650 kWp.

The trigeneration installation covers their entire cooling energy needs (except in the summer when it only covers about 80%), and the electricity produced by the PV panels combined with the trigeneration plant provides for over 50% of their total electricity use.


  • Optimal usage of fuel
  • Reduced production costs
  • Big savings on electricity costs by own generation of energy
  • Less primary energy consumption and lower CO2 emissions
  • More independence from volatile energy market
  • Free source of energy for cooling generation (=waste heat) & PV (=sun)
  • Secure source of electricity and heat
  • No transmission losses as energy is produced and consumed locally
  • Low maintenance costs
  • Long lifespan
