Description

Vertiv GLH-400 Concise Descriptor

Overview

The Vertiv GLH-400 is a compact, thermostat-controlled heater designed to maintain optimal operating temperatures within IT enclosures. It prevents condensation buildup and ensures sensitive electronics operate within their specified temperature range, particularly critical in environments with fluctuating ambient conditions. The GLH-400 is suitable for deployment in standard server racks and network cabinets where precise climate control is required to prevent equipment damage or performance degradation. Its compact form factor allows for easy integration without consuming excessive rack space.

Compatibility

This heater is designed for general use within standard 19-inch server racks and network enclosures. It is compatible with a wide range of rack systems and cabinets from various manufacturers, provided there is adequate space for mounting and airflow. It does not require specific software or hardware integration with network devices; its function is purely environmental control.

Installation Notes

The Vertiv GLH-400 requires a standard AC power outlet for operation. Mounting typically involves securing the unit to the rack frame using provided hardware or standard rack mounting accessories. Ensure adequate clearance around the heater for proper air circulation to prevent overheating of the unit itself and to effectively distribute heat within the enclosure. The unit's thermostat allows for setting a target temperature, typically between 5°C and 35°C, to maintain a stable environment for your equipment.
