SECTION 22 33 13.05 Emergency Eyewash CLE Series

Electric Tankless Eyewash Water Heaters CLE Series Guide Specification

Keltech, Inc. Tankless Eye/Face Wash Heaters provide warm water intended to supply emergency eyewash fixtures. The heaters uniquely perform in applications with low line pressure, while still accommodating ANSI standard flow rates. The durable plumbing components withstand higher pressures which result in a longer service life, while ensuring the delivery of precise output temperature within ±1 deg. F. (0.6 deg. C). Keltech's durable electrical components withstand power abnormalities found in industrial environments and ensure tepid water standards are never exceeded 100 deg. F (37.8 deg. C) with its three-tier anti-scald protection.

Keltech Tankless systems do not require the installation of an emergency thermostatic mixing valve. The NEMA 4 Enclosure (General Area) is durable and waterproof. NEMA 4X Enclosure offers the same features as a NEMA 4 Enclosure, with the added benefit of corrosion resistance. CLE-Series units are also suited to applications where 3 Phase Delta 480V or 600V is required.

Keltech's eyewash water heaters allow eyewashes to quickly reach the required ANSI/ISEA Z358.1 standard for tepid water temperatures 80 deg. F (26.7deg. C) in as little as 20 to 30 seconds and provide injured employees with a consistent flow of tepid water – up to 10 GPM (37.8 l/m) – for 15 minutes.

Redundant Control and Safety Features: Every Keltech emergency eyewash water heater includes multiple safety features including internal fusing, digital microprocessor-based temperature control, an externally mounted emergency stop button, and splash proof NEMA 4 water tight enclosures. Multiple, safety only circuits monitor for over temperature conditions and ensure output temperature does not exceed ANSI standards for eyewash tepid water temperature.
