Environmental rooms can be fabricated in just about any size required. We do have standard sizes, and can make custom sizes on request. Most projects require insulated floors, for which we offer both 4” and 2” thickness.

INTERIOR & EXTERIOR FINISHES

Choose the finish which best suits your application. A new finish is available now which is called Anti-microbial. This finish inhibits the growth of microbacteria and organisms on the interior walls and ceilings. This was originally developed by the Carrier corporation to guard against Legionaires disease in air conditioning components.

This inorganic material has an active ingredient made of ionic silver. The encapsulated silver ions are released to the surface of the treated steel where they suppress the growth of destructive microbes.

After 24 hours, an anti-microbial coated steel surface shows much less bacteria contamination than an un-coated surface. The coating compound maintains its effectiveness over a wide range of temperatures and humidity values.

Anti-microbial-coated steel has completed salt spray testing (ASTM B117), condensing and humidity testing {ASTM 02247} and water immersion testing (ASTM D870). All existing Insulated Structure features and test approvals remain when adding the anti-microbial finish.

In addition to the anti-microbial finish, the following finishes are also available:

White over galvanized
White over aluminum
Stainless steel
Other finishes (Consult factory)

FLOORS

Our 12 Gauge Foamed in place flooring is designed and made for high load capacity. High density foam with the 12 gauge surface holds 1500 pounds per square foot.

Specialty flooring can include a custom 2" thick floor used for reduced pitch at ramps, and complies with handicap entry/egress statutes. Altro Overlay seamless nonskid sheet flooring coved up all sides 4 inches. Also can include NSF Flooring and Diamond Plate Flooring. Metal Finish Flooring also in Aluminum and Stainless Steel.

REFRIGERATION SYSTEMS

Different building configurations and services dictate the type of refrigeration systems that can be utilized.

Water-cooled remote condensing units: This system is commonly used in new construction, where cold rooms are in construction configurations that allow for cooling water to remove heat from the condensing unit depicted here, a roof mounted water-cooling tower recirculates the cooling water down to the condensing unit. The unit may typically be mounted on top of the cold room; however it may also be mounted in an adjacent mechanical space. Refrigerant tubing is piped to the cold room evaporator to complete the cooling process. (Temperature control is still governed by our exterior control panel).

Air-cooled condensing unit removes heat by means of ambient air surrounding the condensing unit, In these applications, It is important to insure adequate free air to properly cool the unit (contact factory for further guidelines), Mounting the air cooled condensing unit outdoors usually allows sufficient air flow, (consult your local representative for more details regarding proper mounting, supports etc,)

Roof mounted air-cooled condensing units allow for unrestricted cooling airflow to the unit, Refrigeration piping is run in the shortest manner possible to the cold room evaporator. This method is limited in permissible distance in proportion to the design temperature deviation tolerance that the project requires. A specialized engineering design will examine the proper line sizing and provisions for refrigerant oil return to insure a well functioning system, Consult your architect for roof loading factors.

Remote air cooled, multi-circuited systems: Where water-cooling systems are unavailable and interior space discourages interior air cooling, remote air cooled, multi-circuited systems are recommended, Numerous cold rooms can be serviced by one or more roof-mounted air-cooled condensers. These will be sized and engineered to cool condensing units that are individually dedicated to their respective cold rooms. Contact factory for more details.

CONTROL PANEL

A compact color display with a digital touch tone screen, the control panel display monitors temperature/humidity set points and actual performance. Multiple screens permit authorized user (code protected) to easily adjust set points alarm parameters, and other key data.

There are NO Exposed conduit or wires and panel operates at a safe low voltage. All unsightly conduit and high voltage connections remain out of sight and away from authorized personnel. Remote-top mount CPU driven, UL508A Approved manufactured complete control panel.

Exclusive built-in electronic charting eliminates the need to change paper and pens. Data can be downloaded into user's PC based system and/or BMS systems.

TEMPERATURE CONTROL

Temperature tolerances are generally +/-1C, although +/- 1/2C is available.

Constant temperature across the working surface, (usually the work table height), is measured using a multi-point recorder. Different specifications will require different approaches to airflow pattern design. +/- 0.5°C is obtainable, while less stringent specifications will result in more economical project costs.

Temperature uniformity is generally measured 40” above the floor, 12” from each wall along a horizontal plane. Gradient temperature is measured vertically, or diagonally.

Gradient temperature differences refers to the deviation in temperature at various points in the room, usually meaning vertically as well as horizontally. +/- 1°C is a generally accepted deviation value for gradient considerations. Shelving storage is often a factor when gradient specifications are called for. The layout and design of shelving, as well as the users storage density on the shelf may predominate the performance anticipated. If precise gradient is a major design demand, it is recommended that the factory is consulted at an early point in the room dimensioning, as height and equipment factors may require size changes to the original scope.

HUMIDITY CONTROL

Dehumidifiers:

Dehumidification is accomplished by utilizing desiccant dehumidifiers which are mounted typically on the exterior top of the rooms and ducted into the room.

For applications where ventilation is constant into rooms, to control moisture accumulation small desiccant dehumidifiers are specified and are ducted into the intake ventilation duct to dry the incoming air.

Where humidity control levels, RH, is specified, our control panel controllers will energize the dehumidifier to satisfy the RH called for.

Humidifiers:

Humidifiers are steam generated and are controlled by our programmable controller. A dispensing nozzle is mounted in the room to distribute the humidity.
