Bell & Gossett Gasketed AP AHRI Certified Plate & Frame Heat Exchangers
- GPX models have higher surface area to volume ratios than conventional shell and tube heat exchangers.
- GPX offers superior heat transfer coefficients compared to shell and tube heat exchangers.
- GPX offers “true” countercurrent flow, which maximizes the mean temperature difference between the fluids
Energy costs and the need to reduce peak energy demand, certifying the performance of air conditioning, heating, ventilation and commercial refrigeration equipment is critical.
Bell & Gossett GPX “AP” plate heat exchangers are certified to the AHRI Standard 400 for Liquid to Liquid Heat Exchangers.
Certification to AHRI Standard 400 establishes definitions, test requirements, minimum data requirements for published ratings, marking, nameplate data, and conformance conditions for liquid to liquid heat exchangers. But most importantly it provides independent third-party certification of performance ratings through yearly testing. All this provides a verified design for the heat exchanger selection insuring performance as specified which protects the customer and engineer on startup, eliminates the need for field testing, and allows system operation with optimal energy efficiency.
Bell & Gossett was one of the first plate heat exchanger manufacturers certified to the AHRI Standard 400 program and has been involved with the development of the program for nearly 15 years.
