Air-Cooled | EDM Chiller | 2 Ton (W/O Pump & Reservoir)

EDM Cooling | Portable Water Chiller for EDM

Model MG-2APT-CH shown. Image shown is typical. Actual unit appearance will vary according specifications and options.

Air-Cooled | EDM Chiller | 2 Ton (W/O Pump & Reservoir)

MG-2APT-CH
  • Provides process fluid temperatures between 20°-80°F.
  • Does not have an internal pump or reservoir. The EDM machine’s pump is used to circulate fluid through the chiller for cooling.
  • Purpose built for the unique cooling needs of EDM machine applications.
  • Designed for indoor installation and air-cooled, using indoor ambient air to cool the process load. No plant or tower water is required.
  • Can be moved between applications and uses non ozone depleting refrigerant.

Specification Notes:
  1. Since product innovation and improvement is our constant goal, all features and specifications are subject to change without notice or liability. Selection of certain optional features may change listed specifications.
  2. Cooling capacity: Rated tons at 12,000 BTU/hr/ton @ 50°F LWT Operating at temperatures below 50° will reduce chiller capacity. The minimum recommended operating temperature when no glycol is used is 48°F.
  3. Ambient conditions: Loss of capacity and/or difficulty operating may occur at higher ambient temperatures. The minimum recommended ambient temperature is 60°F.
