Hamworthy Heating has introduced new plate heat exchangers to support the installation of its Stratton mk3 boiler in commercial premises.
To help support the installation of its new Stratton mk3 wall-hung condensing boiler onto existing heating systems, Hamworthy Heating has announced its latest range of Plate Heat Exchangers – designed to increase boiler protection and performance.
Energy-efficient boilers are now widely used, but there can be an issue when integrating a new condensing boiler into an existing system and pipework. Challenges to consider – pointed out by the company – are potential un-controlled leaks from existing systems causing raw oxygenated water to be constantly added to the system. This further adds to the corrosion of the system and boilers creating problems from blocking heat exchangers with suspended solids and corrosion problems from system metals.
To bridge the gap between old and new systems the company’s Stratton mk3 wall-hung condensing boiler is now available with a range of AHRI certified plate heat exchangers to protect the new boilers from old systems.
Compact solution
Featuring a brazed design with no need for gaskets or supporting equipment, the latest range of plate heat exchangers from Hamworthy Heating offer a compact solution to maximise plant room space and keep the boilers operating at maximum efficiency. The company says its latest plate heat exchangers feature a large surface area with thin plates to provide efficient heat transfer, helping to reduce energy consumption, which in turn, can help to lower energy costs.
The Stratton mk3 boiler features a 5:1 turndown ratio, pre-mix burner technology for clean operation with ErP Class 6 NOx emissions, and up to 97% gross seasonal efficiency. It is backed by a five-year heat exchanger warranty.
Available in seven different outputs from 40 to 150kW, the Stratton mk3can be cascaded to meet building demands or larger installations. In these applications, the company says plate heat exchangers can also be used as a pressure break, where heating, water service, or chilled water is being pumped up multiple storey heights, or in the case of older tank fed systems allows for the hydraulic separation of new to old.
