Users should take care when choosing a drying cabinet for long term, reliable and easy usage with superior performance. A lot of models and different dehumidification techniques may be encountered. Important issues to help you decide are summarized as follows:
Dehumidification rate may be said to be the most important issue to think about when purchasing an automatic drying cabinet. This is the specification of the cabinet which can maintain the set humidity level in a short time or not. Have enough information of the time required to reach the set humidity level after a door opening at your conditions of use. Your main conditions of use include;
An easy and smart user interface helps controlling and monitoring of the cabinet. It should display the humidity and temperature measurements at the same time with the set values. Controlling the user parameters must be easy. Alarm functions should ensure confident operation. History display is a plus to evaluate the performance during operation.
The material used at cabinet body and shelves is also important. Stainless steel shelves and electrostatic painted steel body provides endurance and protection against corrosion and scratches.
Also ask for how air tight the cabinet itself is. This includes the body isolation material, door glass type and if magnetic gaskets are used at doors or not. The glass of thermal insulation type should be used at the doors. All of these would reduce the heat and humidity transfer between the cabinet and the ambient during operation. This benefit brings cost saving and better performance.
Comparing the power consumptions of the cabinets with same features and storage volume may give an opinion about the air tightness and the efficiency of the dehumidification tecnique used in the cabinets.
Regeneration cycles should be well regulated by control unit of the cabinet to optimize the time elapsed for regeneration. Otherwise unwanted high humidity levels may occur inside during these cycles especially in high humidity ambients with frequent door openings.
Some materials require constant temperature besides humidity to store them in their ideal conditions. Ask for a temperature controlled heater feature if you will store this kind of material.
Data Logging / Remote monitoring features are offered by some cabinets. Measured humidity, temperature values; events, alarms are recorded regularly with real time date / hour. These include;It would help the user to monitor a lot of cabinets’ status easily from a PC giving a chance to interfere immediately in case of a failure. A time saving and confident option.
Besides the issues explained above, storage volume, flexibility to put different size material, maintenance needs or no maintenance and the options offered of the cabinet should be considered with the price when selecting the automatic drying cabinet you need.
