The Versatemp EQV units offer a range of five quiet and efficient water to air reverse cycle heat pumps.

The units feature R407C refrigerant, two double inlet centrifugal direct coupled fans with 3 speed sealed for the life motors. Optional fascia (for direct wall mounting installations) made from aluzink and painted in white RAL 9002. Units are designed for ease of installation, service and maintenance.

The units automatically provide cooling or heating to ensure year round comfort. The microprocessor control system also provides other important functions such as monitoring and group control.

Options include cased, cased front entry air, basic for installation behind surround and basic with front entry return air. Plinth, grills and discharge ducts are all available to aid installation issues.

CERTIFIED QUALITY SYSTEM ISO 9001 : 2000

STANDARD UNIT SPECIFICATIONS

COMPRESSOR

hermetic rotary compressor with gas compression in the crankcase, direct suction, no oil heater. It is mounted on antivibration rubber pads. Includes oil feed.

STRUCTURE

structure made entirely from “aluzink” plate that guarantees excellent mechanical characteristics and high corrosion strength over time. The compressor area is made from thick metal plate and is completely insulated with soundproofing material to minimise noise output. The ventilating section is completely lined with anti-condensate and soundproofing material.

PANELLING

external fairing made from “aluzink” plate and powder painted (colour RAL

9002, rough texture), fastened to the unit by two compression hooks and an easily-removable screw, enabling fast access to the internal components.

Where necessary, insulated with anti-condensate and soundproofing material.

AIR EXCHANGER

direct expansion finned exchanger, made from copper pipes in staggered rows and mechanically expanded to the fin collars. The fins are made from aluminium with a corrugated surface and adequately distanced to ensure the maximum heat exchange efficiency.

WATER EXCHANGER

Full copper tube-in-tube exchanger, hermetically welded to the refrigerant circuit.

Checked at a pressure of 30 bars and welded in nitrogen atmosphere to avoid oxidation.

Includes antifreeze protection at water outlet.

Version:

High efficiency (H) plate exchanger brazed-plate exchanger in AISI 316 stainless steel for increased surface exchange with external thermal/anticondensate insulation

FAN

dual intake centrifugal fan with forward blades for maximum efficiency and low noise. Statically- and dynamically-balanced according to the ISO 1940 standards, section 6.3. The scroll, the rotor and the frame are made from galvanized steel plate (semdzimir).

Directly coupled to the electric motor.

REFRIGERANT CIRCUIT

The circuit is complete with:

-liquid receiver

-high pressure switch

-4-way reverse cycle valve

-non-return valve

-expansion device

FILTRATION

NAN honeycomb mesh air filter made from neutral multiply polypropylene fabric (weighted efficiency A –gravimetric method – 48%).

TRAY

Inox steel AISI 304 condensate collection tray with anti-condensate insulation, welded, fitted with drain pipe

ELECTRICAL PANEL

the electrical panel, including the microprocessor controller, is positioned inside the units, with access through an easy-to-remove panel.

the Power Section includes:

-power input terminals

-auxiliary circuit fuse

-compressor control contactor

-isolating transformer for auxiliary circuit power supply the control section includes:

-antifreeze protection

-compressor overload protection and timer

-electronic thermostat for air temperature control

-centralised alarms with remote signalling

-remote ON/OFF control

-complete alarm management with log

-On/off switch

-Active alarm or function signal LED

-terminal block for connection to room thermostat;

-microprocessor control

ACCESSORIES

-manual two-way valve at the inlet and outlet of each exchanger on the water side. Used to isolate the unit from the water circuit to allow any maintenance operations.

-ON/OFF solenoid valve, water side

-serial connection kit for connecting the unit control module to a centralised control system (PC or BMS).

-Versatemp series electronic thermostat (English market)

-remote thermostat

-Versatemp control (english market)

-water flow setter (manual valve)

-painted plinth for floor standing arrangement

-water circuit connection hoses plus condensate drain pipe

-condensate discharge pump

-outlet duct
