Sussman Electric Boilers, a recognized brand within Diversified Heat Transfer, Inc. (DHT), has broadened its EWx Series Electric Hot Water Boiler lineup with the introduction of new models ranging from 30 kW to 240 kW.
This expansion of the EWx platform offers engineers, contractors, and facility owners a more compact and high-efficiency solution for a diverse array of hydronic heating applications.
Features of New EWx Models
The latest EWx models maintain the modular design and digital feed-forward control framework
The latest EWx models maintain the modular design and digital feed-forward control framework prevalent in the larger, existing units.
Their reduced footprint makes them particularly suitable for mechanical and utility rooms with limited space, ensuring the expected high performance and reliability of the EWx line.
Available in both right-hand and left-hand configurations, all EWx models allow zero side clearance, facilitating tight, multi-unit installations where maximizing usable space is a priority.
Commitment to Innovation and Flexibility
Discussing the EWx Series expansion, Neil Pilaar, Vice President of Sales at Sussman Electric Boilers, stated, "The expansion of the EWx Series reinforces our commitment to innovation and to giving customers flexible, future-ready electric heating options."
He added, "By offering a broader range of sizes, we are helping facilities of all sizes move towards electrification without sacrificing performance or installation simplicity."
Next-Generation Electric Boiler System
Jake Goldberg, President and CEO of DHT, expressed, "The EWx platform was engineered from the ground up as a next-generation electric boiler system."
"Bringing these smaller sizes to market is a natural progression of that vision and supports our long-term focus on sustainable, high-efficiency heating technologies."
