The Reznor RTU series
is a range of packaged
Air Conditioning units,
providing cooling and
heating.
Model Range
Reznor's range of high
efficiency packaged
rooftop units are available
in cooling only and
reversible modes. Both
are available with energy
recovery function as an
option.
>>
>>
RTU units come in different models with
cooling and heat pump capacities ranging
from 20 to 300 kW.
Features & Benefits
Acoustic jackets combined with
insulated compressor compartments
>>
Low noise variable speed condenser
fans providing energy efficient
operation and head pressure control
>>
Plug and play controls, compatible
with a range of BMS protocols
including Modbus, and BACnet
>>
Energy analyzer
>>
Variable speed EC fans
>>
Damper actuators
>>
Optimised design for R410A refrigerant
>>
High energy efficiency at both full
and part load operation to reduce
operating costs
>>
Low noise levels achieved through high
performance fans and use of antivibration blocks for the compressor
and refrigeration circuit assembly
>>
Centrifugal fans with optional EC
plug fans for both supply and exhaust
airflow
>>
Active heat recovery option available
to provide enhanced cooling and
heatpump performance
>>
Electronic Expansion Valves driver
modules
>>
Digital-scroll or Inverter Compressor
driver modules
>>
CO2 or VOC sensors and control
Controls
The Reznor RTU utilises Carel Microprocessor Controls to provide automatic operation
of cooling, ventilation, heating and heat
recovery operation. Additional control options inlcude :
>>
Remote control operation
>>
Temperature and/or humidity sensors
(up to 6 units)

Energy Efficiency Multiscroll Technology
Annual energy consumption kWh
Multiscroll technology combined with
electronic expansion valves (EEV) and
EC plug fans increase the system energy
efficiency and provide a resilient and reliable
solution.
Multiscroll technology +
Electronic Plug-fan
Thanks to the RTU's ability to produce its
output in smaller increments, spaces with
a variable occupancy rate and changing
conditions during the day, such as shopping
centres, can benefit from energy savings up
to 30%.
Standard
The RTU range of units come equipped
as standard with high efficiency G4 class
air filters. Fresh air & ventilation options
provide a high level of indoor air quality
and help ensure a clean and comfortable air
conditioned space.
Supply air fan
Compressors
Outdoor fan
Return air fan
The seasonal efficiency of multiscroll units
in tandem from four scroll AC compressors
is similar to the equipment with inverter
compressors. For units with less than four
compressors, high ESEER is achieved thanks
to Digital Scroll technology with refrigerant
flow control.

[DER] Dynamic Energy Recovery. A subcooler
in the DX circuit increases the unit's output by
15% without any additional compressors.
[AER+] Active Energy Recovery + Digital
Scroll: this is Active energy recovery by
a compressor group with Digital Scroll
technology and EC fan.
[AER] Active energy recovery using a separate
DX circuit to recover heat, suitable for exhaust
rates between 20 and 60% of airflow.
