Optimum Capacity

The normal rated capacity of the MF4S when drying 1” hardwood is 10,000BF (8,400 cu ft). The units can be installed singularly or in multiples to provide drying capacity to match any need. The MF4S units are rugged, reliable wood drying systems designed for the larger wood retailer or sawmill needing regular supplies of thoroughly dried wood with minimal delay. The units can be installed singularly or in multiples to provide drying capacity to match any need. Their Stainless Steel Coils make MF4S the ideal choice or drying OAK and other timbers which produce acetic Acid


The rigid tough frames are designed to cope with drying chamber conditions. Specially treated heat exchangers are used to prevent corrosion when drying species containing concentrations of acids, notably Oak.


EIPL MF4S wood dryers are installed inside the drying chamber. This means that all the heat produced as a by product of the drying functions can be recovered and re-used continually throughout the drying run. Running costs are, therefore, low, improving your profitability by reducing costs.


Space inside the drying chamber is at a premium, so the MF4S dryers are slim in shape to allow maximum space for the wood being dried.


The MF4S dryers incorporate design features which will optimize operation in the temperature range up to 140˚F (60˚C). At this temperature the wood will release it’s moisture quickly and in safety. Operation at significantly higher temperatures requires specialized refrigerants and inevitably frequent servicing. EIPL wood dryers therefore, operate in the temperature range which is the best compromise between drying speed and machine reliability. The design of the MF4S allows each unit to operate effectively at low relative humidity levels. This means that you can be sure your wood is thoroughly dried to low moisture contents, 6% if required.


If you need for dried wood grows, so can your drying system. Users can start with a single MF unit and add more later. This arrangement means less strain on your cash flow without the danger of installing a drying system which becomes too small.


MF4S wood drying systems are controlled by the EIPL MCU modular controllers, including microprocessor driven, fully programmable systems. This means that drying is accurately controlled, and you can be certain of high quality dried wood.

Full Feature Syatems

In addition to the basic drying and heating functions, MF systems can incorporate a number of optional features from the EIPL range of supplementary equipment. To minimize further the modest running costs of MF units, drying chambers should be well insulated. Overheating in warm weather is prevented using the EIPL venting unit. To ensure even distribution of heat throughout the woodstack, it is necessary to install supplementary fans inside the drying chamber. EIPL can supply suitable fans from a range of specially selected models.
