26"W x 22"D x 60"H with cold rolled 20 gauge steel sides/back/top/bottom welded to 14 gauge steel undercarriage and powder coated with white, black or grey enamel.Casters add 4” to height of chamber after installation. Shipping weight is 225 lbs.

22"W x 19"D x 41"H with prepainted 040 aluminum sides/top and a stainless steel bottom pan. 10 c.f. capacity.

Two inches of foamed-in-place urethane insulation.

1/5 HP condensing unit is air cooled, hermetically sealed, thermostatically controlled (adjustable) and self-contained, with permanently lubricated fan motor bearings. An electrically commutated evaporator fan motor is used for energy efficiency. Oversized aluminum finned copper refrigeration coils provide rapid cool-down and tight control over selected temperature settings with R-134A as the coolant. The heat from the condenser evaporates condensate produced by the coil. Self defrosting.

ZNXTC-100 Microprocessor controlled temperature range of 2-8C when set to 5C. Uniformity is 2.8C of setpoint when measured in air on the shelves . Large digital temp display with scroll back feature to view past performance in 12 hour graphed increments, audible and visual hi/low alarm with relay (for connecting to a dialer) and a mini SD card for recording data. The mini SD data can be opened in an Excel spreadsheet to view history. Ambient laboratory temperature should be between 60- 80F. Optional spare mini-SD card.

Chamber air is drawn up through the wire shelves and along the door surface to the cooling coils, where it is conditioned to the proper temperature and forced down the rear wall to the bottom of the chamber.

Spring loaded, self-closing, double paned hinged tempered glass door with black PVC frame. Optional door lock or solid door.

Each 21" x 17" shelf has powder coated epoxy steel wire construction capable of supporting 50 lbs. of evenly distributed weight. Shelves attach to pilaster with stainless steel clips. Three shelves are included.

One cool white LED lamp with interior on/off switch and lamp guard.

115/60/1 with standard three prong plug. Draws 3 amps. Max heat output of about 600 BTU/hr.

All chambers are run for 24 hours and evaluated for overall performance prior to shipping. Checkpoints include temperature regulation, verification of alarm and recording thermometer function (if these options were ordered), power usage, electrical ground integrity, reverse polarity, and interior/exterior structure inspection.

All chambers are warranted for one year from date of shipment for parts and workmanship. The warranty does not cover any damages to items stored inside of the chamber due to temperature excursion caused by a mechanical or electrical failure. The compressor motor (part only) is warranted for an additional four years from date of warranty expiration.
