the assist pump(s) will ramp up in speed
ensuring duty point is maintained.
When the system demand reduces to
zero, the pumps will ramp down until
they stop. If the duty pump should fail,
the standby will start and run until
pressure is restored. The Duty pump is
rotated between all pumps after each
operational cycle to ensure even wear.
Specification:
Pumps: Horizontal multi stage design
of stainless steel construction, WRC
approved.
Motor: Totally enclosed fan cooled
(TEFC), IP54, class F, 230 volts, three
phase, direct on line (DOL) starting via
panel mounted inverter.
Inverter: Each pump has a dedicated
panel mounted inveter, giving maximum
reliability and flexibility. The inverters
typically employed are panel mounted 6
pulse PWM type inverter.
Pipe Work: Stainless steel 14571, sized
in accordance with the overall hydraulic
performance of the unit.
Valves: DVGW certificated nickel-plated
isolation and non-return valves.
Pressure Sensor: Heavy duty piezo-
resistive type transducers (4-20ma).
Accumulator: 1 x 8 litre MWP 16 bar, WRc
approved c/w through flow shutoff valve
for testing and draining.
Control Panel: VR-230V central control
unit of fully electronic modular design
for automatic control of a maximum of 3
The WILO Comfort-Vario series of
single phase cold water booster sets
are particularly suitable for use wherever
small quantities require to be delivered
at modest pressures. VR applications
include:
Large dwellings - Small apartment blocks
Hotels - Hospitals - Clinics
Leisure complexes - Caravan sites
Light industrial applications
Description
All units are fully automatic self-
contained pump sets designed to
provide reliable water supplies. The
sets are quiet running, making them
suitable for use in hotels and hospitals.
The control systems are based on
proven electronic technology giving
reliability and simple on site adjustment.
Sets are manufactured with either two or
three pumps operating as duty-standby,
duty-assist, duty-assist-standby and
duty-assist-assist. The pumps, pipes
and controls are carefully arranged on
a steel base frame to ensure that floor
spaced used is minimal, yet maintenance
is easily undertaken.
Operational Cycle:
The configuration of the pumps can be
chosen to suit the specific application:
Duty-Standby or Duty-Assist. System
pressure is maintained by a hydraulic
accumulator and monitored by pressure
a sensor, keeping the system ready for
instant draw off. When demand causes
pressure to drop the duty pump starts,
and will ramp up in speed to match the
system demand. The pump will continue
to run, varying its speed to match the
varying demand of the system. If the
demand exceeds capacity of duty pump

  • 1. Comfort-Vario COR-MHI/VR. Single Phase Variable Speed Booster Sets.
  • 2. 2 the assist pump(s) will ramp up in speed ensuring duty point is maintained. When the system demand reduces to zero, the pumps will ramp down until they stop. If the duty pump should fail, the standby will start and run until pressure is restored. The Duty pump is rotated between all pumps after each operational cycle to ensure even wear. Specification: Pumps: Horizontal multi stage design of stainless steel construction, WRC approved. Motor: Totally enclosed fan cooled (TEFC), IP54, class F, 230 volts, three phase, direct on line (DOL) starting via panel mounted inverter. Inverter: Each pump has a dedicated panel mounted inveter, giving maximum reliability and flexibility. The inverters typically employed are panel mounted 6 pulse PWM type inverter. Pipe Work: Stainless steel 14571, sized in accordance with the overall hydraulic performance of the unit. Valves: DVGW certificated nickel-plated isolation and non-return valves. Pressure Sensor: Heavy duty piezo- resistive type transducers (4-20ma). Accumulator: 1 x 8 litre MWP 16 bar, WRc approved c/w through flow shutoff valve for testing and draining. Control Panel: VR-230V central control unit of fully electronic modular design for automatic control of a maximum of 3 The WILO Comfort-Vario series of single phase cold water booster sets are particularly suitable for use wherever small quantities require to be delivered at modest pressures. VR applications include: Large dwellings - Small apartment blocks Hotels - Hospitals - Clinics Leisure complexes - Caravan sites Light industrial applications Description All units are fully automatic self- contained pump sets designed to provide reliable water supplies. The sets are quiet running, making them suitable for use in hotels and hospitals. The control systems are based on proven electronic technology giving reliability and simple on site adjustment. Sets are manufactured with either two or three pumps operating as duty-standby, duty-assist, duty-assist-standby and duty-assist-assist. The pumps, pipes and controls are carefully arranged on a steel base frame to ensure that floor spaced used is minimal, yet maintenance is easily undertaken. Operational Cycle: The configuration of the pumps can be chosen to suit the specific application: Duty-Standby or Duty-Assist. System pressure is maintained by a hydraulic accumulator and monitored by pressure a sensor, keeping the system ready for instant draw off. When demand causes pressure to drop the duty pump starts, and will ramp up in speed to match the system demand. The pump will continue to run, varying its speed to match the varying demand of the system. If the demand exceeds capacity of duty pump Wilo-Comfort-Vario COR-MHI/VR Single Phase Variable Speed Booster Sets parallel pumps, which contain integrated frequency converters for the speed control. Sheet steel enclosure, IP54 protection class, with door interlocked isolator, LC display, access to operation control parameters via a single dial/ pushbutton. Design: Max working 10 Bar Pressure: Voltage: 230V/1PH/50Hz Protection Index: IP54 EMC Compliance: EN61000-6-2/3
