Lowara: Reliable and innovative HVAC solutions for modern buildings

For more than half a century, Lowara has been a trusted name in water pumping technology, delivering solutions that are reliable, efficient, and easy to install. Founded in 1968 in Montecchio Maggiore, near Vicenza, Italy, the company has built its reputation on material quality, continuous product development, and a strong focus on the needs of industry professionals. Today, Lowara is part of Xylem, a global leader in water technology, and continues to be a trusted partner for building services applications, particularly in the residential, commercial, and institutional HVAC sectors.

For installers, designers, and engineering professionals, Lowara offers a reliable combination of proven technical solutions, expert application support, broad product availability, and technologies designed to simplify installation while improving long term system performance.

A technology partner for high-efficiency HVAC systems

The energy transition in buildings requires HVAC systems that are increasingly efficient, versatile, and digitally connected. In response, Lowara has developed a dedicated portfolio designed to optimize energy consumption throughout the entire lifecycle of a system, enhance comfort, and simplify installation and maintenance.

Lowara's HVAC solutions address the key challenges of both new construction and renovation projects, including:

  • Limited plant room space
  • Retrofit installations on existing systems
  • Reducing operational costs
  • Integration with Building Management Systems (BMS)

Efficient circulation and intelligent distribution: ECOCIRC, e-LNE, and e-LNT

For HVAC circulation applications, Lowara offers the ECOCIRC range of high-efficiency electronic circulators for residential and commercial use. Equipped with permanent magnet motors and integrated electronic controls, ECOCIRC automatically adjusts performance according to actual system demand, significantly reducing energy consumption and noise levels. Its compact design and preconfigured operating modes make installation quick and intuitive, particularly for replacement projects on existing systems.

For larger systems and commercial or institutional applications, Lowara offers the e-LNE and e-LNT (twin-head version) in-line pumps. These solutions are designed to deliver high hydraulic efficiency, operational reliability, and maximum flexibility for integration into HVAC systems.

The e-LNE pumps provide straightforward in-line installation, compact dimensions, and easy maintenance. The e-LNT twin-head models are ideal for applications where redundancy and uninterrupted service are critical, such as public buildings, hospitals, large commercial facilities, and data centres.

hydrovar® X: The intelligent core of HVAC pumping systems

In modern building services, hydrovar® X represents the technological heart of Lowara's high-efficiency HVAC solutions. This variable-speed control platform is compatible with IE5 motors and can manage up to eight pumps in multi-pump configurations. The system dynamically adjusts pump speed according to actual system demand, optimizing energy consumption while reducing mechanical wear.

The combination of a synchronous reluctance-assisted motor and intelligent drive technology can achieve energy savings of up to 70% compared with traditional fixed-speed systems, delivering direct benefits in terms of operating costs, CO₂ emissions, and overall system sustainability. The rare-earth-free IE5 motor also helps reduce environmental impact throughout the supply chain.

From an operational perspective, hydrovar® X offers a compact and modular design, simplified wiring, a multilingual digital display, and parameter cloning functions that enable rapid commissioning of multi-pump systems. Native connectivity (including Modbus RTU, BACnet MS/TP, Bluetooth, Wi-Fi, and Cloud integration) facilitates seamless integration with BMS and remote monitoring platforms, enabling real-time diagnostics and predictive maintenance.

hydrovar® X+ Smart Controller: Intelligent control for a wider range of applications

The next evolution of this platform is the hydrovar® X+ Smart Controller, designed for applications of various sizes, including systems exceeding 22 kW. hydrovar® X+ introduces universal compatibility with any inverter, simplified configuration, and intelligent management of up to eight pumps, making it ideal for both new HVAC installations and retrofit projects on existing systems.

For installers, this means faster start-up times, greater design flexibility, and the ability to modernize aging systems without major modifications to the existing infrastructure. The result is a significant improvement in efficiency, reliability, and long-term system value.

A partner for the energy transition of buildings

As the building sector places increasing emphasis on energy efficiency, decarbonization, and digitalization, Lowara continues to strengthen its role as a technology partner for HVAC applications through a combination of:

  • High-efficiency circulation and distribution products (ECOCIRC, e-LNE, e-LNT)
  • Intelligent control platforms (hydrovar® X and hydrovar® X+)
  • Application support and tools for designers and installers, including selection software, CAD/BIM resources, and technical documentation

Choosing Lowara means partnering with a brand that brings more than 50 years of expertise in pumping technology, backed by solutions specifically engineered to make HVAC systems more efficient, reliable, and ready for the challenges of modern building design.
