The PTA UK Group and Frigosystem Corema: Cooling with Purpose

Since partnering with Frigosystem Corema, PTA UK Ltd has strengthened its portfolio with advanced temperature control solutions. Frigosystem, a historic Italian manufacturer, brings over 50 years of expertise in cooling and process stability—now aligned with PTA UK's commitment to efficiency and sustainability.

As environmental responsibility becomes essential across all sectors, Frigosystem has made sustainability a core pillar of its R&D. Its systemic approach focuses on energy efficiency, operational safety, and long-term reliability.

Smarter Refrigerants for a Greener Future

A key area of innovation is the adoption of low-GWP refrigerants. While traditional refrigerants like R410A remain effective, Frigosystem is leading the way by introducing options like R454B (with 10x lower GWP), R513A, and R1234ze. Each solution is carefully selected for the right balance of safety, performance, and sustainability.

Heat Recovery: Free Energy Within Reach

All refrigeration circuits generate heat during operation. Frigosystem Corema has turned this fact into a concrete savings opportunity, integrating heat recovery systems into its units that convert wasted thermal energy into a useful resource.

These systems allow for:

- Production of hot water up to +80°C, usable for sanitary or process applications;
- Recovery of up to 50% of cooling power as thermal energy;
- Savings of about 1 m³ of methane gas for every 8 kW of heat recovered.

The result is a tangible environmental benefit combined with significant economic returns for end users.

Free-Cooling: Cooling More Efficiently with Natural Weather

Another area where Frigosystem Corema has successfully invested is the optimization of free-cooling, now available across its entire range of water chillers. This technology takes advantage of favorable climate conditions—cool nights, intermediate seasons, winter months—to cool process fluids without relying on compressors, which can then be throttled or turned off entirely.

The benefits include:

- Reduced energy consumption;
- Extended machine lifespan;
- Lower environmental impact;
- Reduced operating costs.

With the current increase in electricity prices, adopting free-cooling has proven extremely advantageous: in some projects, the return on investment has occurred in less than a year, with net savings in subsequent years.

Looking Ahead: Sustainability in Action

Frigosystem’s approach to innovation is deeply rooted in environmental responsibility. From next-generation refrigerants to integrated energy-saving systems, every solution is engineered for a more efficient, lower-impact future.
