Elevated summer temperatures in the Upper Midwest can put added stress on electrical components, leading to equipment failures, reduced life cycles, and unplanned downtime. As a general rule, the life of electronic equipment can be cut in half for every 18°F, or 10°C, above room temperature.

Steiner can help you protect critical equipment and keep operations running with a complimentary nVent HOFFMAN Thermal Audit. This audit helps identify problem areas, provides clear evidence of excess heat, and includes a report with recommended thermal management solutions to help reduce maintenance costs, improve uptime, and extend the life of your electronics. Virtual audits are also available.

Featured Air Conditioners


nVent HOFFMAN SpectraCool | Standard Indoor/Outdoor Series

SpectraCool Standard Series Air Conditioners are designed for robust cooling performance in demanding indoor and harsh outdoor environments. Rotary compressors provide more energy efficiency than reciprocating compressors, and allow quick re-start under pressure without causing damage. Dual impellers on G52 and G57 units pull air into the front of the unit and direct the air upwards in a 90-degree angle for the most direct air path while providing redundancy.

Key Features:

  • 4,000 to 20,000 BTUs/Hr of cooling.
  • Lightweight design; 30 lb. (14 kg).
  • Indoor and outdoor models.
  • Dust-and corrosion-resistant components for trouble-free operation in the most demanding environments.
