Accessories and Options (Cont'd)
QUANTECH
Thermal Dispersion Flow Switch – A thermal dispersion type flow switch provides accu-
rate, low maintenance flow proving and is included standard. It is factory wired and installed
in the extension pipe between evaporator outlet and edge of chiller. The extension pipe is
secured to the chiller frame for shipping to avoid risk of damage to evaporator and is easily
attached to the evaporator at startup using the supplied ANSI/AWWA C-606 connector. The
flow switch can be deleted if alternate or existing flow switch is field supplied.
Evaporator Nozzle Extension Kit – Pipe and ANSI/AWWA C-606 fittings to extend the
evaporator connections to the outside of the chiller. Includes the Thermal Dispersion Flow
Switch. Provided as standard on all chillers but can be deleted if alternate or existing pip-
ing and flow switch is field supplied. The extension pipe is secured to the chiller frame for
shipping to avoid risk of damage to evaporator and is easily attached to the evaporator at
startup using the supplied ANSI/AWWA C-606 connector. A support bracket for the exten-
sion kit or field piping is standard on all chillers. Extension kit insulation and heat trace to be
field provided if required.
Hydro-Kit – Factory installed hydro-kit suitable for water glycol systems with up to 35%
glycol at leaving temperatures down to 20°F. The hydro-kit option is available in a single or
dual configuration (dual as standby duty only), with totally enclosed permanently lubricated
pump motors.
The hydro-kit comes standard with a variable speed drive, a balancing valve, discharge
check valve, discharge shutoff valve, thermal dispersion flow switch, pressure ports, inlet
wye-strainer, bleed and drain valves and frost protection.
Service shut off valves, additional pressure ports and taps for the expansion tank are op-
tional within the hydro-kit option. Expansion tanks are available by request.
CONDENSER AND CABINET OPTIONS
Condenser coil protection against corrosive environments is available by choosing any of
the following options. For additional application recommendations, refer to FORM 150.12-
ES1.
Post-Coated Condenser Coils – The unit is built with electrostatic post-coated condenser
coils. This is the choice for corrosive applications (with the exception of strong alkalies,
oxidizers and wet bromine, chlorine and fluorine in concentrations greater than 100 ppm).
Enclosure Panels (Unit) – Tamperproof enclosure panels prevent unauthorized access to
units. Enclosure panels can provide an aesthetically pleasing alternative to expensive fenc-
ing. Additionally, for proper head pressure control, Quantech recommends the use of Con-
denser Louvered Panels for winter applications where wind gusts may exceed five miles per
hour (8 kph). The following types of enclosure panels are available:
Wire Panels (Full Unit) – Consists of welded wire-mesh guards mounted on the exterior of
the unit. Prevents unauthorized access, yet provides free air flow.
Wire/Louvered Panels – Consists of welded wire-mesh panels on the bottom part of unit
and louvered panels on the condenser section of the unit.
Louvered Panels (Condenser Coil Only) – Louvered panels are mounted on the sides
and ends of the condenser coils for protection.
Louvered Panels (Full Unit) – Louvered panels surround the front, back, and sides of
the unit. They prevent unauthorized access and visually screen unit components. Unre-
stricted air flow is permitted through generously sized louvered openings. This option is
applicable for any outdoor design ambient temperature up to 115°F (46°).
