STC-200 Refrigeration Controller – Reliable Digital Temperature Controls for Refrigeration Systems

Introduction

When you build, repair or retrofit a refrigeration system, the temperature controller is the component that decides whether your equipment holds temperature reliably, wastes energy, or fails under load. For OEM manufacturers and refrigeration contractors who value proven, repeatable performance, the STC-200 refrigeration controller from SHTROL offers dependable digital temperature controls in a compact, economical package that is easy to integrate at scale.

What OEMs and Contractors Actually Need

A refrigeration controller for the OEM market has to balance several requirements at once. It must be affordable enough to keep the finished product competitive, reliable enough to survive years of continuous operation, and simple enough that production-line workers and field technicians can install and set it up without special training. The STC-200 was designed with these priorities in mind. Its compact footprint means it fits neatly into refrigerators, freezers, wine coolers, beverage chillers and vending equipment where space is tight and every millimeter counts.

From the purchasing and engineering perspective, standardizing on one controller across a product family reduces inventory complexity and simplifies documentation. When a single model handles multiple SKUs, your team spends less time on qualification testing, spare parts management and after-sales support. The STC-200 is a stable, long-life platform that supports this kind of standardization, backed by a factory with the production capacity and quality systems to keep pace with your output.

Key Features

The STC-200 is a mini-sized digital temperature controller designed for refrigerators, freezers, coolers, and a wide range of refrigeration equipment. It combines straightforward push-button operation with a clear LED display, giving installers and end users an interface that needs almost no training. Despite its small footprint, the STC-200 supports accurate temperature sensing and stable relay switching, making it a workhorse for continuous-duty cooling applications.

• Compact size for space-constrained OEM installations
• Easy push-button programming with clear LED display
• Wide temperature range for fridge and freezer use
• Reliable relay output for compressor control
• Economical price point ideal for high-volume projects

Who It Is For

The STC-200 is a strong fit for OEM manufacturers building refrigerators, beverage coolers and freezers; for distributors who supply components to service technicians; and for contractors upgrading older refrigeration cabinets. Because it is manufactured in our 10,000 m² facility with a 50+ engineer R&D team and 700+ patents behind the brand, you get consistent quality, stable supply and technical support that scales with your business.

The STC-200 is engineered for long service life. Its robust relay and durable enclosure are built for continuous duty in compressors that start and stop many times a day, and its straightforward interface means less operator error and fewer service calls. For high-volume buyers, this reliability directly translates into fewer warranty claims and a stronger reputation in the market.

A Complete Temperature Control Range

The STC-200 works alongside a wider SHTROL portfolio so you can standardize on one supplier:

• ECS-974T (WiFi Flagship): app-based remote control and monitoring for premium, networked installations.
• STC-100: universal heat/cool controller for refrigeration and heating applications.
• XH-W3001: plug-and-play micro controller for quick field replacements.

With products exported to 100+ countries and annual output of over 1,000,000 units, SHTROL combines production scale with engineering depth to keep your refrigeration systems running at their best. Our team welcomes OEM and distribution partnerships and can tailor packaging and firmware to your specification.

For OEM buyers, the STC-200 also supports flexible customization. We can provide custom panel labeling, tailored packaging and documented firmware behavior to meet your specification and market requirements. Combined with reliable lead times and a committed export team, this makes the STC-200 a low-risk choice for companies that need dependable components at scale.

Quality assurance is another reason buyers choose the STC-200. Every unit is tested before shipment, and the controller is backed by the same ISO-managed production line that supports our entire range. For international buyers, CE and RoHS certifications simplify import and compliance, while our export team assists with documentation, sample requests and after-sales support in multiple languages.
