Non storage (shell and tube) and storage calorifiers
Manufactured in copper, stainless steel or galvanised mild steel for both vented and unvented applications.
Our non storage calorifers, are designed to heat a fluid (usually water) instantaneously as it passes through the heat exchanger. The primary heat exchanger is usually a U-tube removable battery which allows the primary heating medium to pass along to the end of the exchanger and then back again producing maximum efficiency.
Heat exchangers are usually manufactured with a mild steel body and the primary exchangers are copper integron tubes expanded into a brass or steel plate. H
Storage calorifiers come with a range of inner heaters from basic plain tube coils, integron (finned tube) removable batteries which can be maintained and replaced quickly and easily. These inner heaters can be heated by steam, HTHW, MTHW or LTHW from primary heat sources such as steam, gas, biomass or oil boilers or even new innovative technologies such as air and ground source heat pumps. The option for the inclusion of additional heat sources such as solar panels is also available.
Storage calorifiers can be supplied with an inspection opening which is used to view and clean the inside of the vessels to prevent the growth of legionella bacteria, these are available in 3 sizes, 250mm,350mm and 450mm. Pre-plumbed de-statrification pump sets are also available which circulated the stored water to ensure there are no cold spots and prevents the water from stagnation which is again a safety feature to help prevent the growth of legionaires bacteria. Our insulation factory line can even pre-insulate the vessels before they leave us with 50mm Rockwool insulation clad with stucco aluminium, also available is spray foam insulation which is subject to size. Lagging jackets to BS5615 also available.
