Eco-Cold Sliding Low Temperature Door Operators

Eco-Cold 1900-RLS Operator

Developed and designed by Chase Engineers, the 1900-RLS provides exceptional performance in cold storage environments. The 1900-RLS provides field proven safe, dependable operation. Even large, heavy doors operate smoothly and effortlessly. The 1900-RLS incorporates standard features including pre-wired components, variable speed operation with soft start/stop, a rotary limit switch, and a NEMA 4X control box. The soft start feature ensures smooth panel travel on startup, stop and reversing. The rotary limit switch is preset to 90% of travel at the factory reducing installation time and potential mistakes that can occur in the field. Plus, permanently lubricated components and self-diagnostics reduce troubleshooting and maintenance that is typical on many door systems.
