DESCRIPTION

Sunline 2000 units are highly efficient, convertible rooftops. All models have dual refrigerant circuits for efficient part load operation. Although the units are primarily designed for curb mounting on a roof, they can also be slab-mounted at ground level or set on steel beams above a finished roof.

These units are designed and manufactured under ISO 9002 Quality System Certification.

Cooling only, cooling with gas heat and cooling with supplemental electric heat units are available with a wide variety of field-installed accessories to make them suitable for almost every application.

All units are self-contained and assembled on full perimeter base rails. The base rails have holes in the four corners for overhead rigging.

Every unit is completely piped, wired, charged and tested at the factory to simplify the field installation and to provide years of dependable operation. Powder paint cabinets provide an exceptionally durable finish with the 750 hour salt spray process per ASTM-B117 test standard.

All models are available with three different outdoor air damper accessosries:

∙Single enthalpy economizer

∙Differential enthalpy economizer

∙Motorized outdoor air intake damper

All models (including those with an economizer ) are suitable for either downflow or sideflow duct connections. For downflow duct, remove the sheet metal panels from the supply and return air openings through the base of the unit. For sideflow duct, replace the supply and return air panels on the rear of the unit with a side duct flange accessory.

A fixed outdoor air intake assembly is shipped in the return air compartment of all units. The assembly includes a rain hood with a damper that can be set for 10, 15 or 25% outdoor air. With bottom duct connections, the intake damper assembly should be mounted over the opening in the return air panel.

With horizontal ductwork, it should be mounted on the return air duct.

All supply air blowers are equipped with a belt drive that can be adjusted to meet the exact requirements of the job.

All compressors include crankcase heat and internal pressure relief. Every refrigerant circuit includes an expansion valve, a liquid line filter-drier, a discharge line high pressure switch and a suction line with a freezestat and low pressure switch. The unit control circuit includes a 75 VA transformer, a 24-volt circuit breaker and a relay board with two compressor lockout circuits, a terminal strip for thermostat wiring, plus an additional set of pin connectors to simplify the interface of additional field controls.

All gas heat models are built with two heating sections for two equal stages of capacity control. Each section includes a durable heat exchanger with aluminized steel tubes, a redundant gas valve, spark ignition, power venting, an ignition module for 100% shut-off and all of the safety controls required to meet the latest ANSI standards.

The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through a knockout in the piping panel on the front of the unit.

All electric heat models are wired for a single power source and include a bank of nickel chromium elements mounted at the discharge of the supply air blower to provide a high velocity and uniform distribution of air across the heating elements. Every element is fully protected against excessive current and temperature by fuses and two thermal limit switches.

The power supply wiring can be routed into the control box through a threaded pipe connection in the base pan of the unit or through a knockout in the wiring panel on the front of the unit.

D3CG, D3CE specifications

York D3CE and D3CG are innovative air-cooled chillers developed to address the growing demands for energy-efficient cooling solutions in commercial and industrial settings. These models are part of York's comprehensive range of HVAC products, showcasing advanced engineering and cutting-edge technologies designed to optimize performance while reducing operational costs.

One of the standout features of the York D3CE and D3CG series is their high efficiency. These chillers utilize a variable speed drive (VSD) technology that allows the compressor to adjust its speed according to the cooling load. This capability enhances energy efficiency, particularly in varying load conditions, and can lead to substantial energy savings compared to traditional fixed-speed chillers.

In terms of environmentally friendly refrigerants, both the D3CE and D3CG models are designed to operate with refrigerants that have low global warming potential (GWP). This aspect not only supports sustainability initiatives but also aligns with international regulations aimed at reducing greenhouse gas emissions. This makes them an appealing choice for organizations committed to minimizing their environmental impact.

The York D3CE and D3CG chillers are engineered to ensure quiet operation, making them suitable for noise-sensitive applications such as urban environments, hospitals, and educational institutions. Sound-dampening technologies are integrated into the design to minimize operational noise, thus preserving the quality of the surrounding environment.

Another significant characteristic is the advanced control system tailored for these chillers. The intuitive controls interface allows for easy monitoring and adjustment of operating parameters, enabling facilities managers to optimize performance and maintain effective cooling without extensive training.

Durability and reliability are also hallmarks of the D3CE and D3CG series. Constructed with high-quality materials and robust components, these models are engineered to withstand harsh operating conditions and deliver consistent performance over time. Regular maintenance can be managed efficiently thanks to accessible service points, ensuring that these chillers can serve their intended lifespan and beyond.

In summary, the York D3CE and D3CG series stands out in the crowded HVAC market due to their high efficiency, environmentally friendly design, quiet operation, advanced control capabilities, and rugged reliability. These features make them a prudent choice for organizations looking to enhance their cooling systems while adhering to environmental and economic sustainability goals.
