Bemco LDP Thermal Enclosures are always custom. They are environmental
enclosures constructed using the techniques normally employed with
Bemco's LDF Series of Wide Range Expendable Refrigerant,
FL-I Series of Integral Walk-in, and FL-M
Series of Modular Walk-in Chambers. The LDP enclosure illustrated
at left has hinged stainless steel doors, with the protective paper
still in place, and hinged sides to allow full interior access.
LDP Thermal Enclosures are primarily intended for
use with Bemco PTS-V Portable Servo Conditioners and PITC-70/177C
Plug-in Temperature Conditioners. They provide a factory assembled
process, product, or test thermal enclosure optimized for a specific
purpose. They can also be furnished with conductive
baseplates or Bemcoil shrouds, thermally conditioned by Bemco
PCL-III Portable Liquid Chillers, or Bemco HPG
High Pressure Gas Conditioners. Systems
of this type are selected when low temperatures are needed on the
baseplate or shroud while condensation from the surrounding ambient
air must be kept to a minimum.
Modular and Integral Enclosures
Bemco integral chambers, such as the LDF, and FL-I models, include a heliarc
welded, 300 Series stainless steel inner liner, fiberglass insulation,
and a structural steel supported carbon steel outer case
finished in Bemco blue. Stainless steel and other
exterior materials are also available. No asbestos is used in chamber construction.
Bemco modular prefabricated chambers, such as the FL-M models, are assembled
from sectional panels using metal inner and outer skins bonded to
a core of rigid polyurethane insulation. At least three heavy duty
cam-action locks are provided on each side panel. Chamber size is
unlimited, however, exact room dimensions must conform with the sectional
panel sizes offered. These panels come in 11-1/2”,
23”, and 46” standard widths in various heights. Rooms can
be constructed as large as needed and can include partitions and
antechambers. Standard chamber access doors include a heated frame,
a window, and an in-fitting or flush main door to positively seal the
workspace. Large equipment loading doors are constructed by Bemco using
integral welded chamber construction techniques to maintain alignment
and structural rigidity.
Since the PTS or PITC conditioning equipment is reusable, the cost of the
facilities per enclosure is much less than purchasing a purpose built
environmental testing system with built-in conditioning equipment.
These system can include any of the options available with the LDF
Series of Wide Range Expendable Refrigerant, FL-I Series of Integral
Walk-in, or FL-M Series of Modular Walk-in Chambers.
With PTS-V Portable Servo Conditioners, ducts
can be provided to route chamber air to any location on the
chamber wall. Internal
air baffling can be placed to internally circuit the air for optimum
results. Shown at left is a Bemco
FTU style LDP Thermal Enclosure with a bias hinge at the back left
edge and a custom FTU style chamber with an unusual lift-up door
Air distribution control panels and instrumentation
packages to monitor your process, product, or test; integrated with
an LDP enclosure are available. Some of these options are discussed
on the PTS
(Portable Temperature Servo) page of this web site. Bemco HPG,
High Pressure Gas Servos, are offered for those applications that
require higher pressures or more pressure drop in the air loop. Please
request an analysis of your needs from your Bemco Applications Engineer.
