Exploring the AERCO DW+ Water Heater: A Detailed U Tube Guide
The AERCO DW+ water heater is specifically engineered to meet the rigorous potable water heating demands of commercial and institutional environments. This sophisticated system integrates real-time load tracking and responsive controls, ensuring consistent and accurate hot water temperatures even under fluctuating load conditions. Operating on steam, the AERCO DW+ offers a powerful and efficient heating solution.
A key feature of this system is its advanced electronic controls package. This technology allows the heater to maintain exceptional temperature control, with variances held to a mere ±4°F under normal load changes, even up to 25% of the water heater’s capacity. The integrated load monitoring system, combined with a high turndown control valve, ensures precise temperature management without the necessity for bulky storage tanks, blending valves, or other temperature averaging components. For enhanced operational oversight, when equipped with the electronic control system, the DW+ can be remotely monitored and seamlessly integrated with Building Automation Systems (BAS) software.
The DW+ indirect fired water heater is available in three models to cater to varying needs:
- Model #SWDW24
- Model #SWDW45
- Model #SWDW68
U Tube Guide to Features and Benefits of AERCO DW+
This u tube guide highlights the key features and benefits of the AERCO DW+ steam-to-water heater, emphasizing why it’s a superior choice for demanding applications. Each unit boasts a compact, space-saving vertical design incorporating a double wall U-tube heat exchanger. This unique design is critical for safety, ensuring no mixing of steam and domestic water flows can occur without immediate detection. Compliant with stringent codes including BOCA, IAPMO, and NAPHCC, the DW+ is constructed with longevity in mind. All wetted parts are made from high-quality 304 stainless steel, virgin Teflon, copper, or copper alloy, ensuring durability and resistance to corrosion.
Key benefits include:
- Accurate Temperature Control: Maintains temperature within ±4°F, providing consistent hot water delivery.
- Compact Footprint: Requires minimal space, occupying less than 4ft², ideal for installations with limited room.
- Fully Modulating Variable Primary Input: Adapts to varying demand, maximizing efficiency and reducing energy waste.
- Premium Materials: Constructed with All Stainless, TFE, Copper, or Copper Alloy Wetted Surfaces for long-term reliability.
- Certified Safety: UL-listed as a double wall heat exchanger for potable hot water use, ensuring safety and compliance.
- Industry Standard Compliance: ASME- B&PV Code Sec. VIII, Div. 1 Stamped, meeting rigorous industry standards.
U Tube Guide to Options and Accessories for Enhanced Performance
To further optimize your AERCO DW+ system, a range of options and accessories are available. This u tube guide will walk you through some key enhancements.
Domestic Water Storage Tank
ASME certified duplex stainless steel pressure vessels are available to ensure a consistent hot water supply during periods of peak demand. These tanks work seamlessly with the DW+ system to provide a buffer and maintain hot water availability when needed most.
ProtoNode Gateway
For integration with building control and energy management systems, the ProtoNode Gateway is an excellent option. It facilitates communication between the DW+ and your central management system, enabling comprehensive monitoring and control.
ADMS (AERCO Digital Mixing Station)
The AERCO Digital Mixing Station (ADMS) is a smart water tempering system designed to regulate distribution temperature with exceptional precision, maintaining it within ±2ºF. This ensures consistently comfortable and safe hot water delivery throughout your facility.
Steam Traps
Steam traps are crucial for preventing steam from escaping before it condenses, maximizing the efficiency of your steam-to-water heating system in domestic hot water applications. These traps enhance energy efficiency and reduce operational costs.
Configurations:
- Bare Heater: The heat exchanger unit only, with insulation available as an option.
- Packaged Heater: A complete, pre-assembled system ready for immediate connection, including the heat exchanger, patented AERCO steam control valve, and electronic controls package.
- Electronic Controls: AERCO’s proprietary electronic control system features a control box assembly with all necessary circuitry, a flow meter at the cold water inlet for feed-forward sensing, feedback sensors, and a voltage regulator. PID algorithms manage outlet temperature and adjust the control valve for optimal temperature stability. User-friendly digital displays are protected by a lockable clear cover. An over-temperature limit switch is also integrated for safety.
- Modbus Communications: An optional control board facilitates remote control and integration with Building Automation or Energy Management Software via Modbus protocol, using RS-232 or RS-485 ports.
- Dry Contacts: Optional dry contacts provide remote indication of “High Limit Tripped Status”, enhancing safety monitoring.
