A beauty treatment room is a small closed room with one client lying still for a long appointment. Massage oil, wax pots and facial steamers add heat and odour in a volume that has little air of its own. Cool it quietly, with the discharge running along the ceiling rather than onto the couch. Privacy between rooms matters: the indoor unit and the outdoor unit should not carry conversation. An F-gas certified company installs the refrigerant side.
A client lying still on the couch
The person on the couch may be there for an hour, face up or face down, often with a treatment that should not be chilled or dried by a jet of air. Set the vane for ceiling flow and a low fan. If the only result is comfort on high fan, the unit is too big or badly placed.
Wax pots and the third facial
Wax heaters, steamers and a towel cabinet are the heat in the room, on top of two people and a closed door. A survey that ignores the equipment will feel fine at 9am and fail at the third facial.
A bright reception and a dim treatment room
Reception can be bright and busy while a treatment room must stay dim and quiet. Give the treatment room its own indoor unit and its own control. A multi-split outdoor unit can feed several rooms if the pipework and the controls are designed that way.
Sound through a thin salon partition
Sound travels through thin partitions and through a shared ceiling void. A cassette that bridges two rooms, or a thin wall with the outdoor unit bolted to it, will put the neighbour's appointment into yours. Place plant on a wall that is not the head of the couch.
- Keep discharge off the couch and the face hole.
- Size the closed room, not the reception.
- Leave filter access that does not cross the client.
Wax fumes and HSE comfort in the treatment room
Cooling will condense moisture and can knock back a stuffy room. It will not extract wax fumes or solvent from a nail table if one has been squeezed into the same room. Those want a ventilation path. The coil is a comfort device. Staff comfort still sits under HSE workplace temperature guidance, which asks for reasonable comfort and does not fix a single maximum temperature.
A leased salon and the ceiling below
Leased salons need consent for the outdoor unit and the wall core. Condensate must leave to a proper waste. A bottle emptied at the end of the day is how ceilings in the shop below get stained.
Frequently asked questions
Will one reception unit cool the treatment rooms?
Not once the doors are shut. Each closed room needs its own indoor unit or it will overheat during the appointment.
