GENERAL DESCRIPTION

Temperature control is achieved by "bucking" a constont cooling capacity with o variable heat input. High heat transfer ratio and minimum temperature grodienrs result from the action of the Jet-Stir Impellers which ore used to agitate the bath medium.

The bath tank has o capacity of 6% gallons for 12" deep tank and 10 gallons for 18" depth. The bath tank is provided with o drain and overflow. Stainless steel evaporator coils run concentrically around the inside diameter of the tank providing for on effective 12" diameter tank cross section. The tank opening is about 70 sq. in. (more than one half o 12" diameter circle) and is ot the top front of the both. It is accessible by means of o removable lid. The bath tank is formed from 16 gauge stainless steel with o heavier bottom. The both housing is fabricated of 16 gouge steel with mist blue baked enamel finish.

A high limit thermoswitch is provided to protect the both from possible overtemperature.

SPECIFICATIONS

Refrigeration: Cooling is by means of two 3/, HP air cooled hermetically sealed compressors arranged in CI cascade system.

Temperature Control: The temperature controller used is o Hallikainen THERMOTROL Temperature Control- ler (see separate brochure for com,plete details). Controller is located at front bottom of cabinet un- less supplied for external mounting in a separatecase. Controller con be either standard THERMOTROL or decode type.

Dimensions: Both the 12" and 18" depth tanks have the some outside dimensions for housing. These ore 48" wide by 24" deep by 37'/2" high (not inc1udin.g stirrer motor). Top and bottom ore mode of %" thick vinyl impregnated charcoal COLORLITH. Note: At least 4" clearance must be allowed at the rear of the bath for air circulation to fan port and for drain and overflow connections to the bath tank.

Insulation: Low "K" factor closed cell (vapor barrier) foam. Bath Heaters: Fast response AEROROD immersion heaters all located within the bath m,edium to maximize control effectiveness. Heaters total 1150 watts. Control heat selections through o 4 way adiustable switch ore 115, 150, 500 or 650 watts. By adding on additional 500 watts through an auxiliary switch, heating loads then con be 615, 650, 1000 or 1150 watts.

Power Supply: 230 volt, single phase, 60 cycle 20 amperes required.

Stirrers: Two Hallikainen Model 1117 Size 1 Jet-Stir lm,pellers ore used to maximize bath occuron/.

Stirrer Motor: General Electric l/12 HP, 1725 RPM, 60 cycle, single phase, 230 volt, totally enclosed ball bearing. Pull Down Time: When Methanol is used os bath medium, pull down time is approximately 6 hours.

Accuracy: f .002'F. with water as bath medium i: .005'F. with Methanol os bath medium
