Smaller VRF system
J-IIS Airstage:
* Smaller VRF units
* For multi-housing, light-commercial use
* 3- and 4-ton sizes

The J series Airstage VRF line includes the smaller J-IIS series for multi-housing and light-commercial use with
equipment in 3- and 4-ton sizes. Shorter height allows installation in smaller spaces or when condensing units
are vertically stacked. The units are said to provide higher efficiency than equivalent single-fan VRF systems.
The J series systems provide as much as 19.8 SEER and 11.4 HSPF. As many as eight indoor units can connect
to each condensing unit. Eleven indoor-unit styles are available. Indoor units range from 7 kBtu to 26 kBtu.

High-efficiency
circulator

The 0015e3 three-setting, ECM-powered circulator has
a variable-speed, high-efficiency ECM motor
that uses as much as 85% less electricity
than others in its class. Applications include
hydronic systems zoned with circulators
or zone valves. The unit provides three maximumfeet-of-head pressure settings to match system
requirements with a maximum flow of 16 gpm. The
company's BIO Barrier protects the pump from system
contaminants and SureStart automatically unblocks a
locked rotor and purges air from the circulator.

Chilled beams

Tankless water-heater system

The 540P tankless water heater integrates a recirculation pump to provide instant hot water in applications
with dedicated recirculation lines. The pump is controlled with a user interface and multiple pump settings,
which allow customized operation to meet hot-water needs and maximize efficiency. An onboard computer
modulates combustion to provide an Energy Factor of 0.95.
