Dryers:
Since the heat dryers create heats in a factory, it is better to discharge the exhaust heat outside during summer time and blow it inside during winter time to save the cost on air conditioning.

Installing heat insulation:
Installing the heat insulation material around the tank has great benefit in saving energy for both dryer and air conditioner.

Switching to different type of dryers:
Dehumidifier and vacuum type dryers are more effective and create less exhaust heat.

As alternative to dryers:
- Buy dehumidified materials.
- Get help from the material vendor (use damp-proof packing and inject dehumidified air).
- Install gas cleaner.
