Advanced - Custom Heat Management

Large high density buildings move heat around with custom refrigerant/water loops. AF Mechanical has many years of experience with maintenance and service for various types of heat management

  • Fan/coil - Dual temp water loops.

  • Heat pump - single temp water/glycol loops.

  • VRF systems stretching the length of the building.

  • Boiler systems to heat the loops.

  • Cooling Towers which cool the loops.

  • Building Automation Systems to manage each component.

  • Terminal units including Heat Pumps and Fan Coil units.

  • Heat recovery systems using water to water, and air to air.

  • Fresh air supply and exhaust systems.
