Compressed Air Dryers: New Dolomite Series

Zan-Tech are the OMI agents for Southern Africa – quality Italian designed and manufactured equipment to ISO standards. OMI has now launches new compressed air dryers of the Dolomite series. The dryers are distinguished for their innovative technical solutions and an accurate research in the optimization of the production process aimed at containing costs.

Below, a list of the strengths of the new DD series:


OMI quality
To build the DD series dryers we adopt the same professionalism and care our company is used to. Over 25 years of experience in compressed air treatment have allowed us to achieve a high standard of quality that is kept unchanged even in the Dolomite series units.

Reduced prices
The containment of the manufacturing cost is the main reason that led OMI to seek alternative solutions that retain unchanged quality and functionality but reducing the costs of production, with the consequent decrease of the final price to the customer.

New design of the heat exchangers
One of the fundamental parts of the dryer, the heat exchanger, has been redesigned by reducing the amount of components inside, rationalizing their position and decreasing the number of welds. This means lower weight, lower cost and higher reliability as the welds are the parts at most risk of losses.

Repositioning of the components
Another important factor to keep costs down is definitely related to the time and resources used for the production of the machines. By optimizing the arrangement of components within the units is thus greatly reduced the time required for in-line assembly. For example, the vertical arrangement of the heat exchanger has reduced the occupied amount of space making also more accessible the inner of the machine during maintenance.

Cases with less metal sheets and less screws
By simplifying the design and adopting different construction techniques, we have significantly reduced the number of screws and metal sheets while maintaining the robustness, making the disassembly easy to facilitate accessibility on maintenance operations.

No pressure switch and hot gas valve
Thanks to the technology that allows changing the fan speed, the pressure switch and the hot gas valve have been eliminated.

Simplified control panel
The electronic controller has been simplified, while retaining all the main functions that allow you to change some settings, as for the standard series units, and display all alarms.

7 ° Dew point
A dew point of 7 ° is sufficient for many common applications. These performances are among the best when compared to products in the same price range offered by our major competitors. For performances and air flow rates, Dolomite series dryers are ideal for garages, small artisans, small joineries, just to make some examples.
