Fan Coil Kits
Fan Coil Kits
The Caleffi 149 series, the compact pre-assembled kits for terminal units, include all of the devices needed to ensure correct operations on a hydronic system, and have been designed for ease of commissioning and maintenance. The dynamic balancing of the fan coil connection kits is ensured by Caleffi diaphragm-type PICV 145 series, that can be equipped with an ON/OFF or a modulating 0-10 V actuator. The inner dynamic element can easily be replaced to ensure long life to the whole assembly.
The Caleffi PICV features equal percentage control and full stroke modulation. In addition, a unique feature is that the valve does not drop authority even at setting different than 100% open position, thanks to its special internal configuration.
Two three-way valves allow for easy periodic flushing of the system and an integrated cartridge strainer will protect the terminal unit, to ensure maximum performance is maintained. Such valves can be also used for bypass or isolation of the unit.
A calibrated Venturi flow measurement device allows for an easy and precise commissioning phase, thanks also to the user-friendly setting of Caleffi PICV 145 series.
The multiple-size connections (1/2”, ¾”, 1”, 1 ¼”) and the huge available range of PICV make Caleffi 149 series suitable for all systems. The possibility of adding flexible hoses, increases its flexibility of installation.
Care has been taken in the design and development of the units to use the minimum number of joints in order to avoid any potential for water leakages.
All the levers and ports are installed on the side of the kit in order to make it symmetrical for universal installation (the kit can be reversed, so that it always matches the pipe configuration of the unit).

Proud of our heritage - passionate about our future
The Water Regulations Advisory Scheme (WRAS) Approval demonstrates that a particular product is compliant with Water Supply (Water Fittings) Regulations or Scottish Byelaws.
With the proliferation of storing water at high water temperatures i.e. above 60°C or having a storage vessel capable of storing hot water at a temperature exceeding 80°C valves capable of reducing the water supply temperature to a more acceptable distribution temperature must be fitted adjacent to the hot water storage vessel.
