Industrial air conditioning and process refrigeration

Industrial refrigeration is not comfort cooling scaled up — it is part of the production technology. An injection moulding machine running too hot, a CNC laser without cooling, or temperature swings in a semi-finished goods store mean downtime, a scrapped batch and losses in the hundreds of thousands. We design cooling systems from a heat gain balance, not from an equipment catalogue.

Where we start: a thermal audit of the facility

Where others offer to sell and install a chiller, we start by calculating how much heat actually enters the hall. We sum gains from production machinery — in glass plants the tempering furnaces alone can dominate the balance — then add solar gains through the envelope, lighting, people and air exchange. Only such a balance tells you what cooling capacity is genuinely needed and how much reserve to leave for heatwaves.

Undersizing shows up as a lost parameter in July. Oversizing means a chiller cycling continuously at low load — more expensive to buy and quicker to wear out its compressors.

Our solutions

• Chilled water installations (chillers) — plants supplying production machinery, with pump sets, buffer tanks and distribution to process consumers.
• Process cooling of machinery — injection moulding machines, lasers, presses, furnaces, glass tempering and fusing stations.
• Cold and freezer rooms — for the food industry, including frost build-up and air dehumidification.
• Precision air conditioning — for zones with narrow temperature and humidity tolerances, including support areas around cleanrooms.
• Heat recovery — using waste heat from condensers for hall heating and hot water.

Refrigerants and F-gas compliance

Refrigerant choice is a decision for years, not a design detail. Phasing out high-GWP refrigerants under EU F-gas regulation means rising prices and limited service availability for older installations. For new projects and retrofits we show the consequences of the choice across the operating life, including leak-tightness requirements and mandatory inspections.

Service and maintenance

A refrigeration installation without inspections loses efficiency gradually and invisibly — a fouled condenser or refrigerant loss raises energy consumption long before it causes a breakdown. We provide 24/7 industrial service, with response terms fixed in an SLA contract.

Frequently asked questions

How does industrial air conditioning differ from commercial?

In scale, continuity of operation and the consequences of failure. A commercial system delivers comfort; an industrial one holds a process parameter — which is why it is designed with redundancy and for continuous duty.

How do you size a chilled water plant?

From the heat gain balance and the machinery load profile, not from the sum of nameplate ratings. Simultaneity of operation is decisive — consumers rarely all run at once, and designing for the sum means oversizing.

Can a retrofit be done without stopping production?

Usually yes. We stage the works around production windows, often with a temporary cooling source during changeover.

How much can a retrofit of an old installation save?

It depends on the starting point, but the largest gains normally come from variable capacity control, heat recovery and tidying up the controls. The starting point is an energy efficiency assessment of the existing equipment.
