Pumps cut power consumption at Palazzo Grassi in Venice

Thursday, August 16th, 2018 von admin

One of the most important museums of contemporary art in Italy, the famous Palazzo Grassi in Venice, is able to considerably improve its energy balance due to the use of pumps with highly efficient, intelligent drives. The pumps and valves to modernise the heating and air-conditioning systems were supplied by pump manufacturer KSB.

For a building of historical and architectural significance, maintaining a particular room temperature and humidity as well as air quality is a costly and major challenge. After a careful analysis of the energy consumption, those responsible for building management started an extensive refurbishment project in 2015. Planning and installing a completely new pumping infrastructure in a historic building presents a great challenge since the building was not designed for such equipment.

Etaline pump with PumpDrive Eco

This year’s ISH trade fair in Frankfurt will see KSB present a new 230 V version of its motor-mounted PumpDrive Eco variable speed system. Available for motor ratings ranging from 0.12 to 1.1 kW, this new version has been specially tailored to the requirements of HVAC applications.

PumpDrive Eco features sensorless differential pressure control which comes preset for use with Etaline L. All key parameters relating to pump and motor data are also set at the factory. This reduces the time required for pump set commissioning.

Alongside wireless Bluetooth modules for permanent installation supplied optionally, Bluetooth couplers are now also available. These can be plugged onto the service interface of PumpDrive Eco from the outside. This arrangement improves usability by also allowing communication with systems that do not have their own BT interface. The myPumpDrive app enables users to communicate with the system and make settings via smartphone.

DAB: Efficient re-use of rainwater

Friday, May 30th, 2014 von admin

Aquatwin_Top_di_Dab_Pumps_Aprile_2014Combined with rainwater collection systems, the new Aquatwin Top is a pressurisation unit which offers savings in terms of water and therefore energy consumption. The rainwater stored in external tanks supplies all services that do not require drinking water (washing machine, WC…). In domestic applications it is calculated that the daily water requirement is 150 litres per person, in particular due to use of the WC, for cleaning and use of the washing machine, for watering the garden and washing the car. Roughly 50% of this consumption can be provided by rainwater, and the use of this water provides an average cost saving of 50%.
