We bring to you the high temperature heat pumps of air cooled as well as water cooled types which can generate hot water up to 70°C. The Calorex heat pumps are of WRAS approved heat exchangers of marine grade quality. They are fitted with R134a eco-friendly refrigerant.
These pumps are used for applications that require higher temperatures for hot water.
Calorex heat pumps are available in rating output capacity: 30 kW – 120 kW
STELT condensing boiler, made from AISI 316 Ti stainless steel with reverse flame combustion chamber able to produce hot water at a maximum temperature of 110 °C. Connected to pressure jet burners operating on gaseous fuels. Some of the product's main features are related below:
inclined boiler body for condensate drainage support
large cylindrical combustion chamber with reversed flame manufactured from AISI 316 Ti stainless steel, TIG pulse welded, able to withstand acid condensate attack.
stainless steel gas passages with special profiles, placed around the combustion chamber in order to extend flue gas development and consequently increase heat exchange and increase boiler efficiency (obtaining low NOx emissions in conjunction with Low NOx burners)
heat exchange surfaces made from AISI 316 Ti stainless steel, welded with TIG method, consisting of stainless plates characterized by a particular corrugated shape being able to increase heat exchange surface, and facilitate droplet condensate formation allowing adequate drainage.
welded using TIG, MIG and plasma procedures, methods that guarantee stainless steel main mechanical characteristics, without sacrificing corrosion resistance to acid condensation.
flanged flow connection and two system return connections for boiler differential input and ensuring minimum possible temperature to take advantage of condensing benefits even in case of medium-high temperature returns.
flue gas chamber able to collect resultant condensate and discharge it through a water trap connected to a neutralizer (where provided) to the waste water drainage system.
burner mounting plate, for attaching pressure jet burners for gaseous fuels use.
heat dispersion surface insulation with thick glass wool mattress, protected with steel varnished panels that can be easily removed
front door with reversible steel sheet opening thermally insulated with ceramic fiber.
complete insulating casing
WALL condensing boiler, with both European and Italian Patent designed by ICI Caldaie for high power in contained spaces.
Particular boiler geometry together with large heat exchange surfaces allow considerable flue gas temperature reduction resulting in 109% efficiency achievement (referring to PCI and Temp. Delivery/Return 50/30 °C). Latest concept burner, 20% to 100% Nominal Power pre-mix flame modulation. Reduced environmental impact achieved by under 10 ppm NOx emissions.
