NH-4 Heater

Nordson® heated airless and air spray systems utilize the Nordson® Model NH-4 fluid heater to reduce the viscosity of coating materials and increase operating efficiency without adding solvents.

The NH-4 heater is an electrically operated, explosion proof, high-pressure fluid filter. It consists of an electrical enclosure and high-pressure fluid passage body. It is available in twin-passage and stainless-steel models for high viscosity coatings, high flow applications or corrosive materials. It can be wall- or dolly-mounted based on application requirements.

  • Simple design makes temperature setting and monitoring easy
  • Multiple heaters can be installed for increased heating/flow capacity
  • Minimizes pressure loss in high flow/high viscosity applications
  • High-temperature limiter and explosion-proof design provide safe operation; heater components are designed for easy installation and field repair
  • High-fluid velocity and low-watt density provide consistent heating
