YORK ® AIR-CONDITIONING PRODUCTS
Fixed and adjustable roof curbs Hot water coil with control
Ideal for down-flow applications, it is a great help for
installation allowing duct connections, electrical connection
and weatherproofing between the roofcurb and the roof
of the building. Shipped in kit form, it also gives sufficient
height for condensate trap operation. The hot water coil and his control are always fitted, wired
and factory tested. Located in the supply air section,
side or bottom duct connection is possible without any
modification. Complete with an anti-frost thermostat, the
PCB will activate the modulated valve (24V supply, 0 – 10V
modulating signal) in order to get the best comfort. A
jumper will allow using hot water coil as 1st heating stage.
The adjustable roof curbs have the same benefits as the
fixed roof curb, it allows the rooftop to be levelled on a roof
with up to 7° slope (4%).
Side duct flanges Electric heaters
It’s an optional (factory fitted) required when rooftops from
sizes 45-175 need to work with horizontal air configuration.
It’s not required for models 17 to 40.
Composed of easy to install sheet metal panels to allow
ductwork connections on the side of the AHU for horizontal
return air and/or supply air. Available on cooling only and Heat pump units, the electric
heater is protected with two overheats per element.
When the overheat operates, there is a lock out of the
faulty electric heater stage and the PCB starts automatically
another heat stage.
Kit conversion propane High heat gas
This kit comprises replacement burner, pilot injectors
and all necessary instructions for converting the natural
gas burner to propane gas. The nominal pressure of the
propane gas should be 37 mbar. This kit comprises replacement burner injectors and all
necessary instructions to provide high heat capacity for
gas rooftop.
Energy recovery Antivibration mounting kit
Attached to the return air box of the rooftop, a rotary
enthalpy wheel retrieves the energy of the exhausted air
and transmits it to the fresh air intake. A special material
used in the wheel allows that latent heat as well as sensible
heat are transmitted. It is composed by a set of stainless steel springs, to be
assembled underneath the rooftop in a specific position.
Their installation avoids the potential vibration transmission
of the equipment to the building and reduces therefore the
noise level (compressors have their own shock absorbers
delivered as standard).
Indoor fan soft start Return fan
Compact control unit with a motor with AC semiconductors,
designed for soft starting and stopping of three-phase
motors for centrifugal fans. The starting time, the stopping
time and the initial torque are adjusted by mean of
independent potentiometers. Used to overcome high return path pressure drops, works
in series with the indoor fan to maintain the air pressure of
the conditioned space within acceptable levels.
(Only available in models ARx 45-90).
Grill condenser protection Air filters
Metallic frame painted with oven-baked polymerized paint
(800h salt spray resistance) to protect the fins of the coils
from external damages. G4, F6 and F7 filters are available to purify the air in the
room. M1 fire class and manufactured in sheet metal frame,
they are easy to install and clean.
