Air handling units for swimming pools
Casing made from 1 mm galvanised steel double walls, with polyester paint on both sides and 25 mm of fibreglass insulation sandwiched between them. Free-standing frame and hinged doors for access to different sections of the unit. All panels and doors lined with rubber gaskets for airtight seal.
Magnetothermic protection switches for the compressor(s) and motorfan(s) power supply. Automatic control circuit switch. Inlet temperature limit thermostat on dehumidification coil. Double access door for fan.
Complete electrical cabinet, fully wired. Main earth connection. Compressor and fan motor assembly switches. CIATpool electronic control control board, a pGD1 graphical terminal, a TCO user terminal (optional) and sensors. The control can connect to a centralised technical management system through a BMS communication cardThe control also manages a local connection between units through a pLAN maximum of 15 units to communicate data and information. Main functions: • Dehumidifi cation control during operating modes: COOLING / HEATING / AUTO and selection of setpoints. • Permanent control of the operating parameters. • View of the values measured by the sensors. • Timing of the compressors. • Daily and weekly programming. • Anti-fi re safety device. • Operating fault diagnosis and main alarm. Optional functions: This control allows controlling optional elements such as: • Outdoor air damper for refreshing air. • Mixing box for thermal or thermoenthalpic free-cooling. • Auxiliary electrical heaters. • Hot water auxiliary coil. • Air-cooled condenser for DUAL operation. • Management of the AERO version. • Clogged filter detector.
Indoor air circuit
Reusable G3 filter fitted on a frame. Direct expansion cooling coil with copper tubes and aluminium blades, protected by a polyurethane coating. Condensation coil with copper tubes and aluminium blades protected by a polyurethane coating. Stainless steel condensate drain pan with drain port. This pan is tilted to prevent water stagnating and causing health issues. Galvanised metal belt-driven centrifugal fan, with direct drive. Manually-adjusted bypass air damper.
Units equipped with two or three refrigerating circuits: • All the circuits help to dehumidify the air by means of evaporation over a coil with two or three circuits. • One of the circuits condenses on a plate heat exchanger made from special SMO-254 steel brazed with copper, supplied with pool water, thereby recovering some of the energy consumed during the evaporation process. • The other circuit or two other circuits condense, and thereby heat, the cold, dry air over an air-cooled coil placed downstream of the evaporator circuit before sending it on to the optional heating coil. Two or three hermetic scroll compressors (depending on the model) with sound insulation and integral motor temperature protection, fitted on anti-vibration mounts. Thermostatic expansion valve with external equaliser. Acid-resistant dehumidifier filter.
High and low pressure switches. Main switch on electrical cabinet door.
