D3HH 180, D3HH 024 specifications

The York D3HH 024 and D3HH 180 are two prominent models in the York range of commercial heating, ventilation, and air conditioning (HVAC) systems. These units are designed for high efficiency and reliability, catering to various applications in commercial and industrial settings. The D3HH series showcases innovative technologies that enhance performance while reducing energy consumption.

The D3HH 024 model is a compact and efficient unit featuring a cooling capacity of 24,000 BTU/h. This makes it ideal for smaller commercial spaces or where precise climate control is essential. Its modular design allows for easy installation and maintenance, ensuring minimal disruption to operations. The D3HH 024 incorporates advanced inverter technology, which provides variable speed compressor operation. This technology not only enhances comfort by maintaining consistent temperatures but also significantly reduces energy costs by operating only at the required capacity.

On the other hand, the D3HH 180 model offers a higher cooling capacity of 180,000 BTU/h, making it suitable for larger commercial applications. This model is built with durability in mind, utilizing high-quality materials that withstand harsh environmental conditions. The D3HH 180 also features a robust heat exchanger, optimizing thermal efficiency and enhancing the unit's overall performance.

Both models are equipped with smart controls, allowing for remote management and monitoring. These controls facilitate energy management strategies and help in integrating the systems with building management systems (BMS), demonstrating York's commitment to smart technology. Additionally, both units adhere to eco-friendly refrigerant standards, ensuring compliance with environmental regulations.

Another notable feature of the D3HH series is its whisper-quiet operation. Enhanced sound-dampening technology minimizes noise levels, making these units ideal for applications where noise is a concern, such as office spaces or educational institutions.

In summary, the York D3HH 024 and D3HH 180 models stand out in the commercial HVAC market for their efficiency, advanced technologies, and user-friendly features. Whether it's the compact design of the D3HH 024 or the robust capabilities of the D3HH 180, both units provide effective solutions for diverse heating and cooling needs while prioritizing energy efficiency and environmental responsibility. These models are an excellent choice for any business looking to optimize their climate control systems.
