On 1st August 2015 the new limits of Regulation 641/2009 with regard to ecodesign requirements of circulating pumps will come into force. These limits impose an energy efficiency index of EEI < 0.23 for all circulating pumps.
Calpeda, ahead of the entry date of the new limits set by the directive, introduces a new and wider range of circulating pumps.
The range includes three different types of product:
The new NCE-EI circulating pumps replace the previous version of the same name. The new version has been enriched with two new models that have a maximum pump head of 4 or 7 metres, and which flank the already-existing model with a maximum head of 6 metres. The new NCE-EI also has a wider operation mode, making it possible to set 2 proportional pressure curves, 2 constant pressure curves or manual speed adjustment.
The NCE-EA circulating pumps flank the NCE-EI circulator pumps, widening the offer of circulator pumps for heating and air conditioning applications. The NCE-EA models can reach a maximum temperature of up to 110°C and a pressure of up to 10bar, and they are available with a maximum head of 4, 6 or 7 metres. The NCE-EA circulating pumps are characterized by their AUTO operation mode, when the circulator pumps can adjust the operation point automatically and according to system requirements. 3 proportional pressure curves, 3 constant pressure curves or manual speed adjustment are also available. The NCE-EA circulating pumps are standard supplied with a heat-insulating shell.
The new NCE-EL circulating pumps by Calpeda were designed specifically for solar energy applications. The NCE-EL circulating pumps are characterised by their compact design and the fact that the working point can be adjusted from 0.6 to 7 metres or in a proportional pressure manner. The NCE-EL circulating pumps are available with a maximum head of 6 or 7 metres.
