Fridge Thermostet DTB-R135

Description

Product Description: DTB-R135 Air-Sensing Refrigerator ThermostatThe DTB-R135 is a specialized electro-mechanical capillary thermostat used predominantly in dual-compartment or frost-free cooling architectures. It features a coiled fluid-filled capillary tube sensor that monitors changes in air temperature. As the ambient air warms or cools, the internal pressure drops or lifts a physical bellows assembly, opening or closing its electrical contacts.Unlike single-door thermostats that clamp directly onto a freezing ice-plate, the DTB-R135 is designed as an “air-sensing” control. It features an integrated adjustment axle for mounting standard numbered control knobs and operates smoothly on standard 125V/250V AC lines, handling a Full Load Amperage (FLA) rating of roughly 5A to 8A.Key Technical FeaturesTemperature Adjustment Range: Calibrated for a standard operating window of $+3.5^circtext{C}$ to $+24^circtext{C}$ (ambient air cutout thresholds).Electrical Rating: 8A at 125VAC / 5A at 250VAC.Terminal Interface: Standard 3-pin or 2-pin spade male terminal layouts for straightforward drop-in wiring.Control Style: Purely mechanical temperature-responsive switch with no digital microprocessors.Compatible Mechanisms & AppliancesBecause it is an air-sensing switch calibrated for a warmer range than direct-freezer plates, the DTB-R135 is ideal for the following equipment:1. Two-Door (Top-Mount & Bottom-Mount) RefrigeratorsCompatible Mechanisms: Conventional double-door, frost-free, or direct-cool refrigerators across major regional brands (such as Singer, Damro, Sisil, Panasonic, and LG).Application: Typically installed inside the fresh food (refrigerator) lower compartment rather than the freezer box. The capillary tube hangs in the path of the internal airflow to monitor air temperature, cutting off power to the compressor or air damper when the main compartment reaches the target coolness.2. Commercial Cake Showcases & Pastry DisplaysCompatible Mechanisms: Glass-sided deli counters, bakery display cases, and countertop dessert chillers.Application: Bakery items and cakes must stay cool ($+4^circtext{C}$ to $+8^circtext{C}$) but should never freeze. The wide, moderate temperature range of the DTB-R135 makes it the go-to choice for managing these ambient commercial display loops.3. Open-Top Beverage & Seafood Storage CabinetsCompatible Mechanisms: Seafood holding units, salad bars, and commercial beverage coolers.Application: Used to maintain stable above-freezing storage environments where the sensor needs to measure the cooling air currents surrounding the product.4. Fixed-Speed Hermetic AC CompressorsCompatible Components: Standard single-phase 220V induction appliance compressors using a PTC starting relay.Application: The internal electrical switch is rugged enough to directly break the live line powering a small standard compressor motor without the need for intermediate control relays. (Note: It cannot be used to directly control modern three-phase variable-speed Digital Inverter compressors).
