Furnish
a system of humidification indicated on the drawings completed
with:
Steam
Distribution System
Inlet Strainer (optional)
Supply Trap (optional)
Steam Valve and Actuator (optional)
Manifold Traps (optional)
-
Control
- Control Humidistat, Limit Humidistat, Air Proving Device
(all recommended)(optional)
- Operation
of the system shall be controlled automatically to maintain
___% RH at ___degrees F with a tolerance of +/-___% RH.
-
Warranty
system for a period of one (1) year from date of beneficial
use of the owner. Distribution system shall be warranted for
a period of three (3) years.
- Provide
owners manual to cover installation, startup, operating and
maintenance.
- The manufacture
shall guarantee the performance of the system in writing based
on design air volume, temperature, downstream RH, and capacity.
Performance is defined as "bulk" and "last wisp"
evaporation and laminar airflow.
-
Provide
steam distribution system constructed entirely of stainless
steel. Dissimilar materials are not acceptable.
-
All
welding to be done in accordance with ASME Section IX.
- Steam distribution
system shall be pressure tested with steam at operating pressure
or greater, at the factory prior to shipment.
-
Entering
steam will be forced to take two 90 degree turns before reaching
the distribution system (pressure systems only).
-
The
manifold shall be equipped with stainless steel nozzles, press
fitted into the stainless steel manifold. The output of the
nozzle is limited to a maximum of 5 lbs/hr. Exact capacity
of nozzles to be determined based on required evaporative
distance and design psychometric conditions. Nozzles extend
into the center of the manifold to allow only the driest,
hottest steam to be allowed to enter the airstream. Nozzles
must be identical output for entire distribution manifold.
Manifolds with holes or orifices only are not acceptable.
-
Multiple
manifold system shall have header and distribution tubes constructed
as a system: all joints shall be welded - slip joints and
"o" rings are not acceptable.
-
Distribution
manifold shall be unjacketed and allowed to cool to surrounding
temperature when there is no requirement for humidity. Jacketed
manifolds with insulation (extra airflow resistance) or isolation
valve (cracking welds) are not acceptable.
-
Distribution manifold design feature provisions for manifold
trap(s). This trap, which can be either a thermostatic or
float and thermostatic trap (a "P-Trap" will work
with self-generating systems), allows any condensate formed
to exit without entering the airstream.
-
Steam
valve, actuator, traps and strainer to be based on parameters
of the application.
-
Temperature
interlock switch is not required. Any condensate formed within
the manifold will be drained out of the manifold trap.
-
Install
system(s) as detailed on the drawings and/or as recommended
by the manufacturer. Shop drawings shall be provided by the
manufacturer.
-
Manufacturer's
representative shall provide analysis, design, and startup
support of the custom engineered humidification system(s).
-
It
shall be the responsibility of the installing contractor to
furnish necessary control provisions, wiring, and plumbing
as indicated in the manufacturer's specifications and the
appropriate schedules. All wiring shall be in accordance with
applicable sections of electrical specifications and local
codes.
