Indoor Ceiling Concealed Water Cooled Fan Coil Units Easy
1. Ceiling concealed fan coil brief description
The ceiling concealed fan coil units are of low noise, light
weight, compact and low height construction. It is specially
designed to cater for today's low ceiling height residence,
offices, light commercial applications and new or existing building
air-conditioning. All fan coil units are completely factory
packaged with blower fan, motor, chilled water coil, circuited and
terminated pipe connections. All fan coils are completely factory
assembled and ready for field installation.
2. Ceiling concealed fan coil unit main components
Fans are double width, double inlet multiblade centrifugal type.
All fans are statically and dynamically balanced.
Single-phase motors are suitable for different voltages, such as
110V, 115V, 120V, 220V, 230V, 240V.
All motors have 10 percent voltage utilization range and wired to
unit terminal box. Motors are designed for long life.
(3) Drain pan
Dray pan is integrally attached to coil casings and ended with
drain hose. All pans are galvanized for corrosion resistance and
cover the entire coil.
(4) Water coil
Coils are 3-row as standard design together with 4-row design as
option. High efficient aluminum fins are mechanically bonded to 3/8
inch O.D. seamless copper tubes.
All coils are specifically designed and circuited for water use.
All coils are tested at 3.3MPa.
Casing are constructed of heavy gauge steel. Interior surface of
unit panels are acoustically and thermally insulated with
Units are furnished as standard with a 1 inch duct collar to
facilitate connection of the supply air duct.
(6) Return air plenum (optional)
The fan coil unit shall be factory installed return air plenum that
encloses the fan section of the unit. No field fabrication is
required. The return air arrangement is adaptable between bottom or
rear return of the plenum.
(7) Washable filter (optional)
Filter should be accessible from return air grille.
