Q1: What voltages can the ZIMMER
operate on?
A1:
The UL/CE listing is valid for any voltage between:
100 - 277 VAC, single phase for sizes up to 50 kg/hr.
100 - 277 VAC, single phase; or up to 480 VAC, three phase, 4 wire (wye) for
100 - 150 kg/hr sizes.
Q2: At which voltage are the capacities calculated at?
A2:
Capacities are rated based on 220 VAC.
Q3: What is the capacity rating based on?
A3:
The capacity is based on using a 220V power supply and with LPG having a maximum
butane percentage allowed for specific valve Model Selection at an ambient temperature of
104 ºF (40 ºC) for models Z25, Z40 and Z50 and at an ambient temperature of 80ºF (27 ºC) for
models Z100 and Z150.
Q4: Can the ZIMMER
use any mixture of propane and or butane?
A4:
There are three versions of the
ZIMMER
– one for commercial propane (e.g. Z40P), one
for standard LPG 70% Butane/ 30% Propane (e.g. Z40L), and one for 50% Butane/
50% Propane (e.g. Z40S). The
ZIMMER
is not designed for use with commercial
butanes.
•
The P valve is designed to operate with a maximum of 15% Butane
•
The L valve is designed to operate with a maximum of 80% Butane and ideally with
60-80% Butane. Using less than 60% Butane will result in a reduced capacity.
•
The S valve is designed to operate with a maximum of 60% Butane and ideally with
40-60% Butane. Using less than 40% Butane will result in a reduced capacity.
Specific vapor pressure curves are available upon request.
Q5: What is the operating temperature?
A5:
The
ZIMMER
uses self-regulating heaters that are not fixed resistance. This means the
ZIMMER
does not have a fixed temperature setting. The
ZIMMER
will reach its peak
temperature at idle, at which point it will consume the least amount of energy. As the flow rate
increases, heat is drawn from the heaters by the LPG causing the resistance to decrease and
allowing them to produce more energy.
Q6: What is the pressure drop at maximum flow?
A6:
This depends on the tank pressure and ambient temperature. At 100 psig (6.9 bar) the
pressure drop is about 1-2 psig (0.07 – 0.14 bar) for 50 kg/hr model or less flow. For the 100
kg/hr or 150 kg/hr models, pressure drop is about 6 psig (0.04 bar). If using 100 or 150 kg/hr
models in cold climates below 0ºF (-18ºC), visit ASDI website or contact factory for additional
information.
