High reliability and low maintenance

The second-generation Model C Thermal Energy Storage tank also feature a 100 percent welded polyethylene heat exchanger and improved reliability, virtually eliminating maintenance. The tank is available with pressure ratings up to 125 psi.

Simple and fast to install

Developed in response to customer requests for more flexible siting and faster installation of storage tanks, the second-generation CALMAC  Model C tanks can be bolted to each other due to their internal headers and four inch flanges. Internalized headers eliminate most external piping (80 percent) which results in a 20 percent smaller footprint requirement and more siting arrangement flexibility, cutting installation cost and time of installation.
