Hot Water Production Unit Refrigeration Training Equipment Technical Education Equipment

HWPU Hot Water Production Unit Refrigeration Training Equipment Technical Education Equipment

This module for the production of hot water can easily be connected with dissipation modules mod. HEU and EDCU.
TRAINING PROGRAM
• Procedures for:
- water filling and air bleeding from the system
- draining and checking system tightness
- starting the plant and checking the operation of boiler safety and protection devices
• Protection devices of a heating plant
