Industrial Calorifiers
What is a calorifier?
Although the term 'calorifier' is the generic name for a hot water storage vessel, it is also used to describe a vessel working under pressure and more commonly, the large hot water cylinders, which would be found in larger buildings such as schools, hospitals, and other industrial premises where there is a much greater demand for hot water than in domestic premises.
What materials do we use to manufacture calorifiers?
Our calorifiers are usually made from copper, as we believe it's high tolerance to corrosion and excellent anti-bacterial properties, make it a superior material to the alternatives, however, other materials are available on request.
Can we manufacture bespoke calorifiers?
As with all of our cylinders, there is also the option for the customer to specify exactly what heat input(s) they would like their calorifier to be able to use, for example, solar, heat pump, gas/oil boiler or even taking heat from a separate buffer cylinder.
We can offer design drawings prior to manufacture to ensure that all port positions are to the customer's requirements.
We can manufacture calorifiers as either vented or unvented type as well as direct or indirect. Our indirect units are also suitable for heat input from steam systems and can be fitted with a removable 'U' tube battery, however fixed coils are more cost effective. An access manhole or a bolted head can be fitted to aid cleaning, maintenance or repair.
Our polyurethane foam lagging can be applied up to a thickness of 100mm and is the most environmentally friendly type available, with an 'ozone depletion potential' of zero and a 'global warming potential' of one. However, for a more aesthetically pleasing finish, we can offer a steel case with a white finish.
What size calorifiers can we offer?
In addition to the cylinders we manufacture for smaller premises (up to 500 litres) we can offer a number of larger capacity cylinders as listed below. However, such is the flexibilty of copper, we can:
- Offer bespoke heights and diameters where space or water volumes are critical
- Match the kilowatt rating of the coil(s) to the kilowatt rating of the heat source(s) (allowing customizable recovery times)
- Add or omit extra connection ports and/or coils to suit your specification
