Cleanroom Chamber - CL Series

CLO34 Cleanroom Chamber

CL Series Overview

The CL series chambers are used for a variety of research applications. These units are specifically made for a cleanroom environment. The CL series cleanroom chambers include heating and cooling capabilities. These units have lower temperature capabilities than our thermoelectrically cooled units, have associated greater heat removal capabilities, and are ideal for locations where the ambient conditions cannot be controlled very well. These units will also outperform our thermoelectric units where specifications call for fast “open door” recovery times.

CL034

The CL034 is a single-door chamber designed for maximum capacity while still allowing passage through most commercial doorways.

Cabinet Construction

  • Standard model features grade 304 stainless steel 18-gauge, #4 finish
  • 2" I.D access port with access port cover and insulation plug located on side wall of the chamber.

Doors

  • Fully welded and sealed door with magnetic gaskets. Has a heavy-duty grade 304 stainless steel latch that ensures secure closure after door opening

Insulation

  • Entire cabinet structure and doors insulated using minimum 2” non-cfc- polyurethane insulation.
  • Insulation manufacturer utilizes CFC free blowing agent that has zero ODP.

Electrical

  • Unit completely pre-wired at factory, and ready for final connection to a 115/60/1 phase – 15 amp dedicated (recommended) outlet. Unit runs approx. 6RLA under test conditions.
  • A 9 ft cord with NEMA 5-15P plug is included.
  • A sole use circuit is recommended
Shelving

  • Unit also equipped with 3 grade 304 stainless steel shelves
  • Shelves capable of supporting up to 100 lbs of evenly distributed weight.
  • Full height shelf support pilasters, with double oblong holes on ½” centers. Pilasters made of the same material as cabinet interior. Four (4) chrome plated, stainless steel shelf clips to be included for each shelf.

Refrigeration System

  • Unsurpassed temperature control through continuous refrigeration bypass system
  • Refrigeration system factory balanced using CFC free 134A refrigerant
  • Top mounted air-cooled condensing unit
  • Factory pre-engineered capillary tube system with over-sized condenser and evaporator to reduce product pull down time and to consistently maintain interior cabinet temperature (non-adjustable capillary tube system superior to problematic expansion valve).
  • Evaporator- epoxy-coated at the time of manufacture to eliminate the potential of corrosion.
