RLNL-G, RLNL-C/H (15-25 Ton)
The 15-20 ton Mainline RLNL, 3 phase only, Package Air Conditioning units feature earth-friendly R-410A refrigerant. RLNL-G units also feature reheat. Reheat delivers maximum humidity control without compromising desired temperature set point for a high degree of comfort by delivering dry neutral air when in the dehumidification mode. The reheat rooftop maintains humidity levels even when there is little or no demand for air conditioning. The Mainlin Commercial Package Air Conditioners combine money-saving efficiency, whisper-quiet operation, environmental-friendliness and superb reliability to bring you peace of mind year after year. Nothing performs more reliably. It's that simple. This platform provides you with a full line of capacities that are AHRI certified. The design is certified by CSA International.
Additional Benefits
Direct Digital Control
Factory Installed Direct Digital Control (DDC) and sensors which can connect to LonWorks™ or BACnet® BAS systems for remote monitoring and control.
The Scroll® Compressor
All of our residential/commercial package units, regardless of efficiency level, feature the Scroll Compressor. These scroll compressors use a more advanced technology than traditional reciprocating compressors. Scroll compressors with internal line break overload and high pressure protection. Dual stage compressor on all models. They have fewer moving parts; they are quieter, more efficient, longer lasting.
Durable Cabinet
Our cabinets have a powder painted finish that protects them from the harshest weather extremes. There is a one-piece top cover and one piece base pan with drawn supply and return opening for superior water management. Externally mounted refrigerant gauge ports for easy service diagnostics. Single point electrical connections. Hinged major access door with heavy-duty gasketing, 1/4 turn latches and door retainers. Foil faced insulation encapsulated throughout entire unit minimizes airborne fibers from the air stream.
Motor/Fan Motor Mount
Our mount helps protect the fan motor from the elements for longer life. Its design dependability helps reduce vibration and noise. Permanently lubricated evaporator, condenser and gas heat inducer motors. Condenser motors are internally protected, totally enclosed with shaft down design.
Matched Blower/Evaporator Coil Unit
The blower is responsible for the flow of air into your duct work. 12.5 ton uses a MicroChannel outdoor coil and other system components for maximum efficiency and quiet operation. In addition, the coil features rifled copper tubing and enhanced fins for improved efficiency. Single slab, single pass designed evaporator coil facilitates easy cleaning for maintained high efficiencies.
Supplemental Electric Heating Strips
Supplemental electric heat strips up to 75 kW are available (field or factory installed) for periods of extreme cold temperatures. Single point electrical and gas connections simplifies installation.
