Refrigeration Technology for the Chemical Industry: Compliant Cooling Solutions for Production, Laboratories, and More

Whether it’s reactors, distillation, storage, or laboratories: in the chemical industry, the right refrigeration technology determines whether processes run smoothly, safety is ensured, and products consistently meet the desired quality standards. ONI stands for energy-optimized system solutions “from a single source”—from analysis and planning to plant construction and service.​

Chemical processes require precise temperature control, high operational reliability, and compliance with regulatory requirements—from reactor cooling through distillation to storage. ONI integrates refrigeration, HVAC, instrumentation and control, and process water hygiene into a validatable complete system, including lifecycle service.

Benefits for Chemical Industry Customers

Benefits of our chemical refrigeration technology: Why it is so important in chemical processes

  • Validatable, redundant systems with traceable documentation and fast service
  • A single system provider reduces interfaces and contracts and simplifies audits
  • Low-temperature/special refrigeration & ATEX experience in the market: System concepts down to −120°C as well as explosion-proof solutions are well-established in the industry
  • Natural/low-GWP refrigerants & high-capacity systems: Manufacturer-independent planning, including natural refrigerants and solutions for high cooling capacities, ensures future viability and eligibility for subsidies
  • Water treatment (e.g., ONI-AquaClean): Control of biofilm/germs, protection of heat exchangers, and constant ΔT for stable processes

That’s why you should choose ONI

Everything under one roof

Here’s how your project works with us

ONI stands for energy-optimized system solutions “from a single source.” We begin with an on-site analysis of your load profiles, system conditions, and process requirements—from which we identify weaknesses, bottlenecks, and potential savings, and, if necessary, prepare a feasibility study to serve as a reliable basis for decision-making.​

​Next steps:​

  • ATEX/Risk Workshop (medium, temperature, zone)
  • Concept options (refrigerant roadmap, redundancy, free cooling)
  • Business Case + Funding, including testing/acceptance plan
  • Implementation + operational support (KPIs/monitoring)

Challenges

Challenges of Refrigeration Technology in the Chemical Industry: Safety, Media, Efficiency
 

Ensuring process stability and product quality through constant temperatures (24/7)

In chemical production, a stable supply of cooling and heating is essential for keeping reactors and processes within the defined temperature range. This prevents scrap, process deviations, and unplanned disruptions.

Energy Prices & Waste Heat Recovery

Rising energy prices make it important to make effective use of waste heat from industrial processes rather than wasting it. Even low-temperature waste heat (starting at approx. 35°C) can be used for heating, which lowers energy costs and reduces CO₂ emissions.

Cooling Water Quality Affects Costs

Poor water quality increases energy consumption, maintenance, and the risk of downtime. The ONI AquaClean system improves water quality without biocides, reduces contamination, removes particles, and minimizes corrosion, thereby lowering costs.

Questions & Answers

FAQ on Refrigeration Technology in Chemistry

Typical examples include desired temperatures, load profiles, media/fluid data, installation conditions, interfaces (control systems/ATEX), redundancy requirements, as well as safety and documentation requirements.

Through transparent measurement data, stable setpoint control, and optimized partial-load strategies. Many savings result from the ability to specifically adjust operating parameters—rather than operating “on a hunch.”

Often, yes—especially when waste heat can be utilized (e.g., for heating processes, hot water, or facility heating). Whether heat pumps are suitable depends on the temperature range and process integration.

Refrigeration technology is designed for process and machine cooling as well as controlled fluid circuits. HVAC technology focuses more on air quality (temperature/humidity) and indoor conditions—in the chemical industry, these two disciplines often overlap.
