The Reznor RTU series is a range of packaged Air Conditioning units, providing cooling and heating.

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.

Model Range

RTU units come in 27 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

> 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 anti-

vibration 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

The Reznor RTU utilises Carel Microproces-

sor Controls to provide automatic operation

of cooling, ventilation, heating and heat

recovery operation. Additional control op-

tions inlcude :

> Remote control operation

> Temperature and/or humidity sensors

(up to 6 units)

> Energy analyser

> Variable speed EC fans

> Damper actuators

> Electronic Expansion Valves driver

modules

> Digital-scroll or Inverter Compressor

driver modules

> CO2 or VOC sensors and control

Energy Efficiency - Multiscroll Technology

Multiscroll technology combined with

electronic expansion valves (EEV) and

EC plug fans increase the system energy

efficiency and provide a resilient and reliable

solution.

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%.

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.

Comfort - Air Quality and Low Level Noise

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.

Optional pre-filters and F6 to F9 filters can

be provided.

The RTU rooftop can be equipped with

Axitop diffusers for the outdoor fans,

improving operational efficiency and

lowering noise levels.

Number of compressors

[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 using a separate

DX circuit to recover heat, suitable for exhaust

rates between 20 and 60% of airflow.

[AERH] Enhanced Active energy recovery

using a separate DX circuit to recover heat,

suitable for exhaust rates between 60 and

100% of airflow.

[AER+] Active Energy Recovery + Digital

Scroll: this is Active energy recovery by

a compressor group with Digital Scroll

technology and EC fan.

[ERH] Free Cooling using a two or three way

mixing box, with dampers and automatic

controls to use the outside air for free

cooling.

[ACS] Partial condensation energy recovery.

Includes a de-superheater that allows using

recovered heat for sanitary hot water.

[MSC] Multiscroll refrigerant circuit. Available

option for series 2000 and 3000, with

refrigerant circuit with two compressors in

tandem, increases seasonal energy efficiency
