Chiller Unit Product Overview
The right cooling machine for your needs.

HYFRA offers you a wide range of powerful air- and water-cooled chiller units with multiple equipment options that can be customized to satisfy your needs. Thanks to sector-leading HYFRA microchannel technology, our chiller solutions are highly efficient and deliver significant energy savings. And they use up to 60% less refrigerant. HYFRA cooling machines are also very compact: outputs of up to 28 kW are possible on bases of only 0.5 m², up to 80 kW on 1 m² and up to 160 kW on only 2 m². This results in significant flexibility advantages when planning production area layouts and a productivity boost as well.

HYFRA Control Units

The right controller for your requirements.

 

We equip our chillers with control units that meet our customers’ requirement profiles.

 

The HYFRA eChilly, Alpha c and Sigma c series come up with the robust ST 120 standard controller with two relays for temperature monitoring and compressor actuation.

 

The chillers in the HYFRA Sigma, Alpha and Gamma series are equipped with FreeSmart or FreeEvolution (from 210 kW power) control units. The two variants are freely programmable and have both analog and digital inputs and outputs, an external display (FreeEvolution) and an FDO interface for quickly reading out operating data. FDO stands for “fast digital output” and is used to switch modulating injection valves, for example. As standard, both controllers feature collective fault signal and external switch-on.

More Output for Your Process Chillers

Our reliable industrial cooling systems have safeguarded and accelerated production processes in a wide range of sectors for over 35 years. For laser technology, filtration and machine tool applications in particular, HYFRA process chiller systems are first choice when precise, reliable compliance with process temperatures is required. Thanks to their compact construction, HYFRA components can be flexibly integrated into any production layout. Innovative technologies such as the HYFRA microchannel reduce energy and refrigerant consumption make our cooling systems highly efficient. Multiple equipment options means our process chiller units can be customized to satisfy your needs.

Machine Tool Applications

A variety of HYFRA chillers can be used to cool machine tool applications. The HYFRA Gamma and HYFRA Alpha series are ideal for cooling machine tools with emulsion or oil. The HYFRA Sigma and HYFRA eChilly series enable a closed cooling circuit for spindle cooling, for example.

Laser Chiller

HYFRA Sigma series laser chillers are the favorite choice for cooling the various components of laser machines.

Filtration Cooling

HYFRA Gamma and HYFRA Alpha chillers are primarily used for cooling various filtration applications in these industries.​

Recycling

Individual and demand-oriented process cooling for recycling machines

Environmental protection and sustainability are becoming increasingly important. Neither companies nor governments can afford to ignore this trend today. When possible, it would be preferred to not dispose of waste and obsolete items in an thoughtless manner, filling huge rubbish dumps, but instead to make as much material useful again.

Space-Optimized Cooling Solutions for Modern Production Environments

The optimization of space in production environments is particularly important in the industrial chilling sector. HYFRA therefore offers plant operators comprehensive advice on space-optimized cooling solutions. The specialist for industrial process chilling provides information on ways to integrate specific cooling concepts in different plant layouts. The Lennox subsidiary is thus responding to the trend for more flexible and efficient production environments and the associated planning challenges. The size and footprint of the chiller, for example, are also important. Thanks to their compact design and reduced footprint, HYFRA cooling systems can be used for a wide range of applications and offer excellent cooling capacity in the smallest of spaces. In addition, thanks to the smaller footprint, the operator can set up additional machines if required, which significantly increases plant output.

 

This is also reflected in HYFRA’s industry portfolio. The HYFRA Alpha circulating chiller is mainly used in filtration and offers a cooling capacity of up to 80 kW on a floor space of 1 m2 – the “Reduced Footprint” version is particularly space-saving, providing a cooling capacity of up to 16 kW over an area of just 0.5 m2. The HYFRA Sigma recirculating chiller is particularly suitable for cooling laser and machine tools, with a power range from 5 to 28 kW over 0.5 m2 up to 320 kW over just 4 m2. Both the HYFRA Alpha circulating chiller and the HYFRA Sigma recirculating chiller are also available as particularly space-saving compact versions with a height reduction of up to 40%.

 

“For many companies, the focus of planning is now no longer only on the intelligence of production systems, but also in part on reduced footprints. Thanks to their power density, our HYFRA Alpha and HYFRA Sigma chilling machines are future-proof and, with their reduced size, allow for more flexibility in system planning” says Berthold Adomat, Technical Manager at HYFRA.
