Technical features of Calido

REFRIGERANT GAS R134A

ENERGY CLASS IN HEAT
The energy saving process was considered an essential aspect while studying and projecting of these units. The very low energy consumption levels together with the high efficiency of the compressors, heat exchangers and the use of the ecologic gas, guarantee to the most part of the models an A" energy class mark.

HOT SANITARY WATER
The installation of a supplementary exchanger working as a condensator in parallel to the air-condensating battery allows a hot sanitary water production independently from the unit working mode.

Technical Features

• Steel tank with double layer vitrification.
• Anti-corrosion magnesium stick for assuring the durability of the tank.
• Condenser wrapped externally to the boiler, free from fouling and gas-water contamination.
• High thickness polyurethane foam (PU) thermal insulation.
• Outer shell made of grey colour plastic material.
• Acoustically isolated top part plastic cover
• Highly efficient compressor with the R134a refrigerant.
• High and low gas pressure protections.
• Electrical heater available in the unit as a back-up (with integrated thermo cut out with protection set at 90°C), assuring constant hot water even in extreme cold winters.
• ON-OFF contact for starting the unit from an external switch.
• Weekly disinfection cycle.
• Electronic expansion valve for precise control

Advantages
• The actual set of the heat pump is controlled by a climate curve for preventing that the hot air taken from outside (over 25°C with water at 65°C, over 35°C with water at 55°C) may cause high pressure alarms.
• The electrical heater integrates automatically the temperature of the tank to the desired setting when the actual setting is controlled by the weather curve.

Flexibility and Benefits

Waste heat recovery: the unit can be installed near the kitchen, in the boiler-room or the garage, basically in every room which has a large number of waste-heat so that it has the higher energy efficiency even with very low outside temperatures during the winter.
Hot water, cooling and dehumidification: the unit can be placed in the laundry room, in clothing room, gym or garage When it produces hot water it lowers the temperature and dehumidifies the room as well.
The function for which the unit has been designed is only that of heat pump for DHW production. Any other side effect (ambient cooling, dehumidification, waste heat recovery) should be considered as a perk. The performance data are therefore provided only with respect to the function of water heating
