*Both 5 KW and 10 KW heat available in all models
**Some units can be used with 200-220/50/1 current at reduced capacity without modification. They can also be modified for use at 220-240/50/1 and/or to maintain full rate capacity at 50Hz. Many other electrical configurations upon request.

III. Options

DMC standardizes its products to speed delivery and to enable us to offer products that can serve most tough applications without the delays and additional costs of making these additional features, options.

However, many applications need at least minor changes to the basic products — most commonly to the electrical configurations, to add heat, and to make them safe for hazardous areas. Therefore, DMC offers a number of options.
