Mayekawa and SWEP build a high-capacity propane chiller for sustainable AC

The customer: Mayekawa, a Japanese multinational, founded in Tokyo in 1924, specializes in eco-friendly thermal solutions for industrial refrigeration and HVAC.

The challenge: Build a large-capacity chiller to provide sustainable laboratory air conditioning for a business complex in São Paulo, Brazil.

The solution: Mayekawa, in collaboration with SWEP, designed and installed a 100 TR (ton of refrigeration) propane chiller.

The heat exchangers: Two SWEP DP300 models from the L-series brazed plate heat exchanger range.

The results: Sustainable, efficient, high-capacity cooling with a low-GWP, natural refrigerant.

Focus on sustainable refrigeration

Mayekawa is focused on sustainable, environmentally-friendly solutions to refrigeration and HVAC challenges. All of the company’s thermal solutions are built around natural refrigerants: ammonia, carbon dioxide, water, hydrocarbons, and air. Mayekawa’s commitment to this approach supports sustainable development, while helping to reduce ozone depletion, and prevent global warming.

With this in mind, when the company was asked to build a new air conditioning system for a laboratory in São Paulo, Brazil, they opted to install a 100TR-capacity propane chiller that provides high levels of sustainable, efficient cooling.

The role of SWEP brazed plate heat exchangers

SWEP’s brazed plate heat exchangers provide the perfect evaporator solution for Mayekawa’s propane chiller. This project employed two SWEP DP300 models from the L-series range of BPHEs. The DP300 is a highly effective, versatile, True Dual evaporator that is perfect for chiller applications. Equipped with patented SWEP AsyMatrix^TM technology, the evaporator’s asymmetric channel configuration smartly combines maximum heat transfer on the refrigerant side with minimum pressure drop on the secondary side.

Why choose SWEP?

Compared with conventional heat exchangers, SWEP BPHES feature increased energy efficiency and better use of structural material, making them a more sustainable solution in suitable applications, including chillers and domestic gas boilers. With a shared mindset of providing more efficient, sustainable solutions for multiple markets, SWEP and Mayekawa were the perfect match for this project.
