Packaged Voyager™ Rooftop Systems 27½ to 50 tons
This line of package units begins with 27½ and includes 30, 35, 40, and 50 ton units. This factory-assembled product is available in cooling-only or in heating/cooling combination models. A package unit is a heating or cooling unit that is self contained.
Voyager™ commercial units contain the best compressor technology available, in order to achieve the highest performance possible. Trane-built scroll compressors are designed specifically to ensure system quality
ReliaTel controls provide unit control for heating, cooling and ventilating utilizing input from sensors that measure outdoor and indoor temperature.
The TCI is available factory or field installed. When applied with ReliaTel, this module easily interfaces with the Trane Integrated Comfort™ System.
The LonTalk Communication (LCI-R) offers a building automation control system with outstanding interoperability benefits.
BACnet Control Interface (BCI-R) for Voyager Commercial offers a building automation control system with outstanding interoperability benefits. BACnet, which is an industry standard, is an open, secure and reliable network communication protocol for controls, created by American Society of Heating, refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE).
A differential pressure control system, (Statitrac™), shall use a differential pressure transducer to compare indoor building pressure to outdoor ambient atmospheric pressure and shall turn the exhaust fans on and off and modulate the barometric exhaust dampers to control the building pressure to within the adjustable, specified dead band that shall be adjustable at the RTVM board.
A unit with the hot gas reheat option shall consist of the following refrigeration components: a hot gas reheat coil, a cooling modulating valve, a reheat modulating valve, a reheat check valve, a reheat pump out solenoid, and additional interconnecting tubing.
In cooling mode, the cooling modulating valve is fully opened and a reheat modulating valve is fully closed. All refrigerant is directed into the outdoor condenser coil. A reheat pump out solenoid is energized allowing trapped refrigerant in the inactive hot gas reheat coil to be directed into the active cooling portion of the circuit. A reheat check valve prevents refrigerant from flowing into the reheat coil.
In reheat mode the cooling and reheat modulating valves direct refrigerant into the hot gas reheat coil and outdoor condenser coil. The cooling modulating valve mirrors the reheat modulating valve position. As the reheat modulating valve opens more refrigerant is directed into the hot gas reheat coil and less is directed into the outdoor condenser coil. The two valves are controlled to a customer selectable discharge air temperature. The reheat coil is located downstream of the evaporator coil and upstream of the supply fan. As more refrigerant is directed into the hot gas reheat coil, the discharge air temperature increases. When in reheat, mode the reheat pump out solenoid is de-energized.
Tool-less, hail-protection-quality coil guards are available for condenser coil protection.
All Aluminum Microchannel condenser coil protection shall consist of a corrosion resistant coating that shall withstand ASTM B117 Salt Spray test for 6000 hours and ASTM G85 A2 Cyclic Acidified Salt Fog test for 2400 hours. This coating shall be added after coil construction covering all tubes, headers and fin edges, therefore providing optimal protection in more corrosive environments.
Variable Frequency Drives are factory installed and tested to provide supply fan motor speed modulation, as well as modulating gas heat. VFD’s on the supply fan, as compared to inlet guide vanes or discharge dampers, are quieter, more efficient, and are eligible for utility rebates. Available with or without a bypass option, bypass control simply provides full nominal airflow in the event of drive failure.
Modulating gas heat models with VFD's allow tighter space temperature control with less temperature swing.
For light commercial applications, Trane offers constant volume (CV) Voyager Commercial models with a changeover-bypass VAV system. For the most advanced comfort management systems, count on Trane.
Trane provides true pressure independent variable air volume with Voyager Commercial delivered VAV. The system is auto-configured to reduce programming and set up time on the job.
Single zone VAV is designed for use in single zone applications like gymnasiums, auditoriums, manufacturing facilities, retail box stores, and any large open spaces, where there is a lot of diversity in the load profile.
Single Zone VAV (SZ VAV) is an ideal replacement to “yesterday’s” constant volume (CV) systems, by reducing operating costs while improving occupant comfort. SZ VAV systems combine Trane application, control and system integration knowledge to exactly match fan speed with cooling and heating loads, regardless of the operating condition.
Trane algorithms meet/exceed ASHRAE 90.1- 2010, SZ VAV energy-saving recommendations, and those of CA Title 24. The result is an optimized balance between zone temperature control and system energy savings. Depending on your specific application, energy savings can be as much as 20+%.
Note: Building system modeling in energy simulation software like TRACE is recommended to evaluate performance improvements for your application.
SZ VAV is fully integrated into the ReliaTel Control system and is available today. It provides the simplest and fastest commissioning in the industry through proven factory-installed, wired, and tested system controllers. All control modules, logic and sensors are factory installed, and tested to assure the highest quality and most reliable system available. This means no special programming of algorithms, or hunting at the jobsite for sensors, boards, etc. that need to be installed in the field. Single zone VAV is a quick and simple solution for many applications and is available from your most trusted rooftop VAV system solution provider- Trane.
Motors with internal Shaft grounding rings can be used with VFDs to provide a conductive
discharge path away from the motor bearings to ground.
The economizers come with three control options: dry bulb, enthalpy and differential enthalpy.
The heat exchanger is manufactured using optional stainless, or standard aluminized, steel with stainless steel components for maximum durability.
The unique design of the scroll compressor allows it to be applied in a passive parallel manifolded piping scheme. When the unit begins stage back at part load it still has the full area and circuitry of its evaporator and condenser coils available to transfer heat. In simple terms this means superior part-load efficiencies (IPLV) and lower unit operating costs.
All of Voyager’s designs were rigorously rain tested at the factory to ensure water integrity. Actual shipping tests are performed to determine packaging requirements. Units are test shipped around the country. Factory shake and drop tested as part of the package design process to help assure that the unit will arrive at your job site in top condition.
Provides exhaust of the return air when using an economizer to maintain proper building pressurization. Great for relieving most building overpressurization problems.
The dedicated design units (either downflow or horizontal) require no panel removal or alteration time to convert in the field — a major cost savings during installation.
U-shaped airflow allows for improved static capabilities.
A single electrical connection powers the unit.
Available for all units.
All Voyager Commercial units have cooling capabilities down to 0°F as standard.
