Greenfloor offers a number of pump and mixing stations to
satisfy the needs of each individual installation.
FRS pump and mixing station
The FRS standard pump and mixing station features a fixed
value thermostatic injection valve, which is commissioned
on site by the installer to the specification provided by
the Worcester Design Service. The flow water temperature
will be maintained constantly at a safe and efficient level.
The FRS also includes a high limit thermostat to protect
the heated floor area from excessive temperatures using a
circulating pump and temperature gauge. Each installation
of an FRS will also require an FRS connection set, available
from Worcester, to allow an easy and speedy connection to
the Greenfloor stainless steel manifold.
Alternatively, a choice of advanced controls featuring
weather compensation is available.
VRS pump and mixing stations
The VRS weather compensated pump and mixing stations
are available to suit up to both a 7kW and 10kW installation
and fit directly to the Greenfloor stainless steel manifold.
The VRS station features a modulating circulating pump,
electronic mixing valve and an intelligent controller. This
feature, through input gathered by the supplied flow
temperature and outdoor sensors, adjusts the output
temperature based upon external conditions.
KMS pump and mixing stations
The KMS remote pump and mixing stations feature the
same proven components and method of operation as
the VRS pump and mixing stations. The KMS provides
the flexibility of mounting the station away from the
Greenfloor manifold and is available to suit up to both
15kW and 25kW installations.
All Greenfloor pump and mixing stations are provided
with comprehensive installation, commissioning and
user instructions. Further support on planning
and specifying the system can be provided by the
specialist Worcester Design Services team.
Single room extensions
The RMS pump and mixing station is designed to offer a
simple underfloor heating control solution for single rooms.
The RMS connects into the existing flow and return circuit
of the central heating system and features a circulation
pump and a temperature limiting valve on the return side.
It is possible for the circulation pump to be electrically
supplied via a proprietary room thermostat to provide an
interlock as well as to aid energy efficiency. Please note
that the RMS single room pump and mixing station relies
upon the existing central heating system’s controls to be
‘calling for heat’ to achieve warming of the floor. To achieve
a greater level of independent control, an FRS standard
pump and mixing station should be selected.
