Fridge Thermostet AWTB-133

Description

Product Description: AWTB-C134 / ATB-Y134 Deep Freezer Thermostat The AWTB-C134 / ATB-Y134 is a specialized mechanical capillary temperature controller built for high-inductive loads. It utilizes a long, liquid-vapor filled capillary tube sensor probe to measure physical thermal shifts. When the probe reaches its calibrated cold threshold, internal pressure drops, prompting the heavy-duty mechanical bellows to snap open the high-voltage circuit. Unlike the R132 or R135 models which are calibrated for warmer fresh-food zones, the C134/Y134 series features a much lower temperature spectrum specifically intended to maintain sub-zero freezing climates or heavy-duty chilling environments. It features a standard 2-pin electrical layout and a standard 6mm rotary D-shaft for control knob mounting. Key Technical Features Temperature Spectrum: Calibrated for deep-freeze cut-out configurations (typically dropping well below −10 ∘ C to −20 ∘ C depending on the exact dial placement). Electrical Capacity: Heavy-duty contact structure rated at 125V/250V AC with a Full Load Amperage (FLA) of 8A / 5A to sustain the intense inrush currents of large inductive motors. Terminal Interface: Simple 2-pin male spade connectors (along with a chassis ground tab) for straightforward drop-in wiring. Operation: 100% mechanical fluid-expansion design with no electronic processing required. Compatible Mechanisms & Equipment Because of its deep sub-zero temperature profile, the AWTB-C134/ATB-Y134 is not suited for standard fresh-food fridge spaces (where it would freeze your vegetables solid). Instead, it is highly compatible with the following mechanisms: 1. Standalone Commercial Deep Freezers & Chest Freezers Compatible Mechanisms: Industrial chest freezers, sliding-glass ice cream bunkers, and meat storage top-loaders (brands like Singer, Innovex, Damro, and Haier). Application: The capillary tube is routed into the interior cavity and secured firmly against the inner wall lining. It keeps the compressor firing until the internal environment reaches a solid freezing temperature safe for long-term meat and ice cream preservation. 2. Commercial Bottle Coolers & High-Capacity Showcases Compatible Mechanisms: Double-door beverage merchandisers and fast-chilling pub glass coolers. Application: Used in setups where beverages need to be rapidly brought down to ice-cold temperatures right above freezing, handling the heavy thermal turnover of commercial retail shops. 3. Fixed-Speed Hermetic Compressors (Direct Line Control) Compatible Components: High-horsepower single-phase AC refrigeration compressors running on external PTC or magnetic start relays. Application: The internal electrical points are robust enough to directly switch the main line feeding large appliance compressors without burning out the contacts. (Note: It cannot be used to directly cycle three-phase variable-speed Digital Inverter compressors). 4. Cross-Compatible Part Families In the global appliance repair trade, this part can replace or be cross-referenced with various deep-freeze capillary lines: Interchangeable Models: AWTB-F133, ATB-Y134, WPF series freezer stats, and Saginomiya deep-freeze equivalents featuring similar-length capillary wires.
