Nilfisk Scrubber Dryers Have ECA WTL Approval

Nilfisk has claimed that it has the greatest amount of water-efficient scrubber driers approved on the Enhanced Capital Allowance (ECA) scheme's Water Technology List (WTL). A total of 49 Nilfisk models are now certified and listed on the ECA WTL. Models range from the 450mm BA451 through to the 860mm ride-on scrubber dryer the BR855.

Models are approved with the benefit of the automated chemical dosing system EDS - Eco Dosage Solution. The government is encouraging the use of green technology by setting up tax incentive schemes for companies that purchase qualifying equipment. The initiative encourages the use of environmentally friendly cleaning machines, and in particular water-efficient scrubber dryers.

Nilfisk has been working with ICCMA and Defra to define the scheme. The ECA scheme allows businesses to claim the whole cost of the qualifying equipment against corporation tax in the first year.

For larger companies, this allows them to save 28 per cent in the form of a tax allowance. Qualifying machines are listed, by model, on the WTL and the manufacturers entitled to use the WTL logo where appropriate. All companies, irrespective of size or industry segment, can claim. Claims can only be made on investments in new and unused plant and machinery.

DS Refrigerant Dryers Reduce Energy Consumption

Boge has brought out a range of energy-saving refrigerant dryers. The DS series features components used in compressed-air drying. Optimally dimensioned components assure reliability and efficiency, even in the most demanding conditions. The DS series dryers also constantly adapt to changes in ambient and volume flow to ensure dry compressed air is always delivered.

At the same time the intelligent heat-exchanger system creates a lower pressure drop when compared with conventional systems. This low-pressure drop means that the compressor generation pressure can be reduced, with each 1 bar pressure reduction translating into a six per cent energy saving. By ensuring the lowest possible pressure loss, a high level of energy efficiency can be achieved.

As the energy consumption of the compressor is greater than the dryer, these savings have a much larger impact and so increase the efficiency of the compressor. It is estimated that over a five-year operating period the purchase price of a compressed-air dryer accounts for only about a third of the total cost. A third of all costs are spent on the electricity required to run the dryer for five years. A further third is consumed over a five-year period by the compressor in order to overcome the dryer's pressure drop.

With the Boge DS series, lowest possible pressure losses reduce energy consumption year on year, impacting on the associated electricity used year on year. The DS dryer control continuously adapts the dryer operation to the real operating conditions.

This ensures continual energy saving. The new DS series dryers are compact and have been designed for ease of maintenance. The DS series has a standard 3C pressure dew point and a flow capacity from 7.5 to 180m3/min. The range is environmentally friendly, emits zero ODP and low GWP and is Montreal Protocol compliant.
