The CONLIFT family has recently had a new model added to it and now besides the CONLIFT1 and CONLIFT2 there is a new cost effective entry level model the CONLIFT1 LS.

This new model has a few less features than the CONLIFT1, but still offers a range of benefits including easy installation, low noise operation and superior reliability.

All CONLIFT models are supplied with an integrated NC/NO contact and cable so that if the overflow switch detects a high water level this can be used to switch off the boiler. CONLIFT2 options include an acoustic alarm in case of a high water condition. They also have a selector switch with additional options.

The advanced design of the CONLIFT range means they work automatically when condensate enters the collection tank from an appliance. The units then lift the condensate up to 5m in height and across a distance of several metres to the required drainage point. Another plus is that these units require minimal maintenance.

The range consists of 4 variants and all versions come complete with a maintenance-free motor including thermal overload protection.

CONLIFT1 LS, is the latest addition to the robust and very popular Grundfos condensate removal range. Based on the strong and highly featured CONLIFT1, CONLIFT1 LS is a cost-effective, entry-level model, still capable of removing condensate in a wide variety of applications.

CONLIFT1, this version, includes a wired alarm contact which can be used to activate an external alarm device or to switch-off the condensate source in case of high water level inside the unit.

CONLIFT2, the advanced version, comes with the same functionality as CONLIFT1 but also incorporates an integrated alarm that gives an acoustic signal in case of high water conditions. These models also offer a selector switch with two options.

CONLIFT2 pH+ comes with the functionality of CONLIFT2 plus a flexible neutralisation unit for particularly aggressive condensate from oil condensing or larger gas boilers to protect the building and the sewer system.

Thanks to the modular system, CONLIFT1 and CONLIFT2 can be upgraded with either an alarm PCB and/or neutralisation unit which can be retrofitted in case changing conditions require this flexibility.
