Choosing Shuntec open & closed loop dehumidification air source heat pump dryer for drying bamboo products is a wise choice, because this unit overcomes the shortcomings of the closed drying systems. The open and closed loop drying system is not affected by the ambient temperature. When the temperature is set, the open-type and closed-type drying methods are intelligently switched, and the sensible heat and latent heat recovery system avoids the low heating efficiency in low temperature environment, which means even if the environment is at a low temperature, the dryer can heat up very quickly without electric auxiliary heat.
