AC 300/WAC300

The Thermozone 300-series consists of the ACvariant in both heated and ambient only format andthe hot water heated WAC model.

These models are designed for permanenet hori-zontal installation over doorways of heights between2.5 and 3.0 metres or positioned vertically beside thedoorway when overdoor space is limited. They can besurface mounted or recessed into a false ceiling. A jetof air from the air curtain prevents cold draughtsthrought open doorways and increases comfort levelsin the proximity of the door whereas the ambient airvariant has been specifically designed for cold storeapplications and entrances to airconditionedbuildings to prevent the loss of refrigerated air.

The use of a Thermozone 300 air curtain enablesthe use of floor space close to the doorway and cansignificantly reduce energy losses giving largesavings. The Thermozone 300 range can also be usedfor industrial heating and drying applications. Forwide doorways, several units can be mounted next toeach other and regulated with a common thermostatand control panel.

The Thermozone 300 series is manufactured inlengths of 1.0 and 1.7 metres which can be combinedto best cover a particular doorway. For doorwayswhich are fitted with ceiling mounted sliding doors,adaptation sets are available that direct the airflowclose to the opening.

� Corrosion proof houing made of hot zinc-plate andpowder enamelled steel panels. Colour: RAL 9016.

� Compact design for installation where space islimited.

� Adjustable mounting brackets for optimisation ofair stream.

� Easy access to connections.

Thermozone 300 air-curtains are specifically designed toprotect and heat the exposed entrances of shopping mallsand department stores and will perfectly complementautomatic sliding doors and double door entry systems.

This H&M store occupies a prime location in the heart ofStockholm. The use of Thermozone 300 air curtains toreplace doors in an eight-meter wide entrance has enabledunhindered customer access and improved the potential ofthis presitgious site.

Thermozone 300 can bemounted vertically at theside of an entrancedoorway and shielded fromshopping carts or smallertrucks using an optionalbarrier. With the telescopehood between the topmostunit and the ceiling, and acovering hoop between theunits, you get anaesthetically pleasinginstal lat ion.

At the Golden GateVIP entrance, at theStockholm GlobeArena, the red carpet isalways rolled out.Every measure hasbeen taken to ensurethat guests feel a littleextra welcome,including twoThermozone AC300units to ensure that thewelcome is alwayswarm.

Smaller industrydoors are effectivelyprotected by aThermozone AC/WAC300. A pleasantand draught-freeworking environmentcan be maintainedeven when the doorsare frequentlyopened.

At a loading bay, doors areoften open for prolongedperiods. Cold draughts canthen significantly effect theinternal temperature.Thermozone 300 is anexcellent complement togaiters in counteractingdraughts and saving energy.

POSITIONING, MOUNTING AND INSTALLATION

Different unit lengthsensures coverage of all doorwidth.

Installaton in false ceiling.

DIMENSIONS

Mounting above doorwayWith the supplied mounting consoles, ThermozoneAC/WAC300 units may be fitted in several ways: onthe wall, on the ceiling, on a cable ladder, etc. Theconsoles make it possible to angle the unit for optimalefficiency. They can also be mounted in false ceilings,see sketch nr 2. Among the hot water heated models,WAC301 and WAC302 are mounted in horizontalpostion above the opening. For minimum mountingdistance to doorway, see sketch nr 1 for theelectrically heated models. The units must not bemounted directly below a power point. For maximumperformance the units should cover the whole widthof the opening and be fitted as close to the openingas possible. Several units can be mounted next toeach other to form a continuous air curtain.

Mounting below ceiling-mounted sliding doorsWhen mounting above openings with ceiling-mounted sliding doors, a square-shaped air curtain

Two towers of verticallymounted, with sideblowingunits.

unit cannot be positioned close enough to theopening because of the opening radius of the slidingdoor. The adaption set AXT401/402 is dome-shapedand may therefore be positioned up against the doorwith the outgoing air stream very close to theopening.

Mounting at the side of the openingWhen space above the doorway is limited, modelsWAC301V and WAC302V can be mounted vertically,thus creating a side blowing air stream. Mountingplates AVMP300 are mounted between units andbetween the lowest unit and the floor. For minimummounting distance to doorway, see sketch nr 1 for theelectrically heated models. For maximum performancethe units should cover the whole height of theopening and be fitted as close to the opening aspossible. Several units can be mounted on top of eachother to form a continuous air curtain. Maximumbuilding height for vertical units without structuralsupport, is 3.5 metres.

VR 20/25, valve set For regulation of water flow to hot water heatedair curtains.

The valve set consists of the following:� AV20/25, stop valve� JV20/25, adjustment valve� TRV20/25, on/off 3-way motor valve� BPV10, by-pass valve� SD20, actuator on/off 230V~

The stop valve (AV20/25) consists of a ball valvewhich is either open or closed. It is used to turn thewater flow off and on. The water flow can be fine-tuned manually with the adjustment valve (JV20/25).It can also be completely turned off. Through apressure outlet the flow can be measured. The kvvalue for JV20 is 0,13�5,9 and for JV25 0,17� 8,52.The 3-way motor valve (TRV20/25) consists of anactuator and a housing. When the TRV20/25 isclosed, the flow through the by-pass valve is low toensure presence of hot water in the heating coil. Thisleads to instant heat supply when needed and somedegree of frost protection. Actuator SD20 works on/off.

The valve set is available with two different valvedimensions: VR 20 - DN20 (3/4�) and VR 25 - DN25(1�). The by-pass valve dimension is DN10 (3/8�). Toregulate VR20/25, a suitable thermostat has to beadded.

TVV20/25, 2-way regulation valve TVV20 has a pipe dimension of DN20 (3/4�) andTVV25 of DN25 (1�). Pressure class PN16. Maximumpressure 2 MPa (20 bar).Maximum pressure fall TVV20: 100 kPa (0,1 bar)Maximum pressure fall TVV25: 62 kPa (0,062 bar)The kv-value is adjustable in 3 stages:

SD20, actuator on/off 230V~ SD20 regulates the heating. Works on/off. A 5 secondclosing of the valves prevents sudden pressurechanges in the pipe system. (IP40).

TVV20/25, 2-way regulation valve and SD20, actuatorprovide a basic form of water regulation without thepossibility of adjusting or shutting the water flow off.A suitable thermostat is choosen to regulate TVV20/25 and SD20.
