Elevated summer temperatures in the upper midwest can cause electrical components to experience increased stress leading to equipment failures and reduced life cycles. As a rule of thumb, an electronic's life is cut in half for every 18°F (10°C) over room temperature. Get trusted expert advice on how to maximize the life cycles of your electronic devices and keep your business running by adequately controlling the temperature of your electrical components when you REQUEST A COMPLIMENTARY NVENT HOFFMAN THERMAL AUDIT FROM STEINER.

A thermal audit quickly identifies problem areas and offers compelling evidence of excess heat that can affect performance and potentially damage your critical equipment. A report with recommended optimal thermal management solutions will be delivered to help you minimize downtime and reduce maintenance costs. Virtual audits are also available to help keep your equipment and you safe.

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.

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.
