All Models
All models are self-contained machines with robust
steel framed cabinets and attractively injection
moulded plastic front, side and top panels. An IEC
Power Lead is supplied for connection to the IEC
socket located at the rear of all models (An
additional Schuko type is supplied for the
European market).
Chilled
Water is fed into the insulated cold tank under
mains pressure. We strongly recommend a
Pressure Reducing Valve is fitted to all supplies to
regulate the pressure to 3.5 bar/355 KPat. The
cold tank is chilled via the evaporation coil of the
capillary controlled refrigeration compression
system. The cold temperature is thermostatically
controlled via the adjustment screw on the cold
thermostat. This is factory set and it is not
necessary to adjust in most cases (see Controls).
Ambient
Water bypasses the cold tank for the ambient
dispense.

Controls
Sparkling
Water is chilled as it passes through the Direct
Chill coil. It is pumped under pressure into the
carbonator which is fitted within the Direct Chill
coil. The carbonator is also level controlled. The
Deep Sparkle effect occurs through saturation with
CO2.
All models also incorporate a leak detection
device within the unit which disables the dispense
function until rectified.
Hot
Hot water is provided by a hot water tank with an
integrated heater element. The water is supplied
directly into the tank under the pressure as
connected into the back of the unit. The water fills
the tank and hot water is dispensed by
displacement. The water flow is controlled by a
solenoid.
Direct Chill
Borg & Overström Direct Chill utilises innovative
technology to chill water instantly. We recommend
this system for more demanding environments
because of its optimum dispense performance and
unrivalled hygienic qualities. Superior to the gravity
fed Reservoir system, Direct Chill technology chills
water on demand for the ultimate drinking
experience.
