WLA Compact – Small size and superior reliability

by | Jul 2, 2024 | Industrial Refrigeration, News | 0 comments

The WLA Compact liquid coolers available in six models with power ratings from 1 to 5 kW find application in numerous sectors due to their advantages of high efficiency, stability and environmental friendliness. With the continuous development and advancement of technology and the growing awareness of environmental protection, liquid chillers will play an even more significant role in the future in process cooling, medical and research laboratory sectors.


Thanks to the optimised component layout and advanced technical solutions used, WLAcompacts guarantee

  • Space-saving: compact design and small footprint, suitable for installation in confined spaces, against a wall or under a workbench.
  • Easy maintenance: the simple structure with fully removable side panels allows easy access to the components of the refrigeration and hydraulic circuits. The operating indicators of the hydraulic circuit (tank level and pump pressure gauge) are easy to read as they are positioned on the front panel and allow operators to intervene promptly in the event of a malfunction.
  • Stability and reliability: High-quality components and manufacturing processes ensure stable, long-term operation. The flow switch and standard automatic hydraulic bypass valve protect the pump and hydraulic circuit and guarantee system reliability.
  • Maintaining a high quality of the process fluid and no corrosion: the hydraulic circuit made of non-ferrous materials reduces the risk of corrosion and reduces maintenance and downtime costs.
  • Dynamic Set Point Function: the unit automatically adapts to various operating situations thanks to the dynamic set point function, adjusting the fluid temperature according to the ambient temperature.
  • Smart Laser function: the microprocessor manages the on/off cycles of the hot gas valve based on the output temperature offset, maintaining precise control of the process fluid temperature even under varying thermal load conditions, with a hysteresis of +/-1K or 0.5K.


The main applications of WLAcompact units are very diverse and extend to different industries:

  • Machine tools: for improving the precision and durability of instrumentation.
  • Food and beverage: to guarantee the safety and quality of the finished product.
  • Plastics processing: moulding and extrusion.
  • Welding systems.
  • Laser: where the purity of the cooling fluid is crucial to preserve the quality of the beam.
  • Printing: for better print quality.
  • Medical: for maintaining the safety and precision of instrumentation.
