Unison Laboratories, Thailand


Unison Laboratories Co., Ltd. has been one of Thailand’s leading pharmaceutical manufacturers for more than 60 years. This success is mainly due to the commitment to produce high quality products at the most affordable prices for the society.


We have been tasked with replacing an older competitor brand screw compressors HVAC system with more energy efficient chillers.


The main challenge was to design an HVAC system that would guarantee high efficiency performance at a competitive price and that would ensure an excellent return on investment.


For this project we have developed two air-cooled Circlemisers with oil-free centrifugal compressors and cylindrical condensers for a total 844 kW (240 RT).

This is the first installation in Thailand of Cirlcemiser chillers, an exclusive technology that is characterized by an innovative design allowing unparalleled performance and efficiency. Just think that it is possible to reach this cooling capacity with machines that have an installation surface of only 3460 x 2100 mm (136.22 x 82.68 in).

The HVAC system developed for Unison achieves EER levels of 3.6 (W/W)*.

*Cooling kW/RT = 0.98 – Cooling EER BTU/Wh = 12.28
