SPECIFICATION
Note: The information provided here is a supplement to the equipment specifications for Benchtop series models.
1. Additional utilities information:
The recommended power on the equipment specification is the system’s full-load amp draw with no factor of safety.
The system is provided with an 8 foot electrical power cord with plug. The plug style is as follows:
MODEL Plug type
BTL-433 NEMA 5-20
BTX-475 NEMA 6-20
BTU-133 NEMA 5-20
BTU-433 NEMA 5-20
BTZ-133 NEMA 5-20
BTZ-175 NEMA 6-20
BTZ-475 NEMA 6-20
The installation spacing requirements for operation are as follows:
Sides: 4”
Rear: No clearance required for operation.
Top: 18”
The average humidity water usage rate varies depending on the set test conditions.
Model Size Example: continuous 85°C/85%
BTL/X-4 1/3 to 1/2 gallon per day
Water used for humidification must be of high quality. Micro-Seamens (abbreviated µS on our specification) is a rating of
conductivity for water. The lower the conductivity, the higher the quality of the water will be. ESPEC offers a “de-ionizing” filter
option installed in-line to meet the minimum quality required, assuming low mineral content in the supply water. It is recommended
to have your water quality analyzed by a water conditioning company for additional purification options. Warning: If the water is
too pure, it can actually be corrosive, creating holes in the chamber’s stainless steel liner.
2. Cabinet features:
The exterior body of the Criterion series is stainless steel 430, which is still magnetic for easy hanging of notices.
The door is thermal formed plastic for durability. The door is painted metallic, slate blue.
The door latch is an ergonomic designed combination cam latch system for convenience and positive door sealing.
The interior chamber liner is 304 stainless steel. The chamber is insulated with a combination of high temperature fiberglass and
Urethane foam. The interior is equipped with shelf pilasters to accept optional wire shelves.
The doorframe is made of an unsaturated polyester material that creates a thermal break between the test conditions inside and
the ambient conditions outside.
Each model can be ordered with an optional multi-pane window (6 inch x 6 inch view area) installed in the door. The window is
heated, to keep the viewing glass clear during low temperature or humidity conditions. An interior chamber lamp is provided to
illuminate the workspace with the window option. Note: The standard model comes without a window and without a chamber light.
