The challenge

Chemical plant needed fast fix when heating and cooling failed

A contract manufacturer of high quality fine chemicals faced a conundrum. Its heating and cooling had failed – so they couldn’t control the temperature of glycol, which is crucial for the chemical reaction. As a result, production had stalled. Problem was, their equipment was obsolete, so there were no parts available. They needed a fast fix to get the plant up and running again.


Project fact file

17 °C

Ideal temperature of glycol solution

100 kW

Heat-pump chiller

The solution

Aggreko heat-pump chiller and 3-way valve keep glycol temperature constant

Our specialist temperature control engineer devised a heating and cooling system that would keep the glycol solution at a steady 17°C (63°F) – the optimum temperature for the chemical reaction. The automated system could easily switch between heating and cooling, and used a heat pump chiller to save on space.

The impact

Aggreko keeps plant running without the need for costly new equipment

Our cost-effective configuration kept the glycol solution within +/-0.3°C of the desired 17°C – giving the chemical manufacturer the confidence to resume production. What’s more, Aggreko’s system could flex for future batch processes, so if another chemical process needed a different temperature, we could easily deliver.


“Every step in the chemical manufacturing process is tightly controlled. We knew how critical it was to get the temperature just right.”
