Designed for residential pumping systems, e-Power ensures constant pressure and reliable operation, even in complex multi-pump installations.
HidroService is a Uruguayan company specialised in the installation, maintenance and servicing of pumping systems. In designing pressurisation systems for residential and commercial buildings, the company selects the most suitable pumps for each project and integrates electronic control solutions tailored to the real operating needs of the system.
More than ten years ago, after a careful evaluation of the alternatives available on the market, HidroService chose Mac3 as its inverter supplier. While e-Power was initially chosen as a technically sound and economically balanced solution, this choice gradually evolved into a stable and strategic partnership. Today, e-Power is the standard inverter used in all pressurization systems designed by HidroService.
The challenge: ensuring reliable performance in a high-demand residential settings
A residential complex required a pumping system capable of guaranteeing constant pressure across multiple floors, despite variable flow rates and fluctuating demand throughout the day.
The project involved a complex installation structured into eight independent booster sets, each requiring precise and reliable control:
- 7 booster groups, each using 3 FORAS Plus P9-250 pumps
- 1 booster group using 3 FORAS Plus P7-V180 pumps
The complexity of the system called for an inverter that could combine hydraulic performance, service continuity, ease of use and effective multi-pump management.
The solution: e-Power
Designed specifically for residential water systems, the e-Power inverter directly addresses the needs of large-scale projects and offers features that simplify advanced control and on-site operation.
Constant pressure control
The variable speed drive automatically adjusts the pump speed based on real-time demand, maintaining a stable water pressure.
Fast commissioning
Only two essential parameters are needed for start-up, making configuration simple and significantly reducing commissioning time, even in complex installations.
Integrated pressure sensor and IP65 protection
Ideal for pipe-mounted installation, even in humid environments or technical rooms with poor ventilation, typical of large residential complexes.
Multi-pump management
e-Power can manage up to 8 pumps in parallel, ensuring automatic alternation at each restart and automatically excluding any pump in case of a fault.
System protection
Integrated protections – including protection against dry running, over/under voltage, short circuits, overcurrent, insufficient pressure, sensor failure and water hammer – minimize downtime and unplanned maintenance.
Key benefits
Operational reliability
Stable pressure on all floors of the building, with no noticeable fluctuations for end users, even during simultaneous peak demand.
Reduced operating costs
Automatic speed regulation lowers energy consumption and mechanical wear. Combined with the integrated electrical protections, this reduces the need for extraordinary maintenance, improving overall system continuity.
Installation speed
The simplified configuration allowed HidroService to commission all eight booster groups in a short time, optimizing workflow and on-site resources.
HidroService found in e-Power the solution it was looking for: an inverter capable of managing complex residential installations while maintaining reliability and the essential ease of use required for field operations.
Looking ahead: an evolving partnership
The collaboration between HidroService and Mac3 continues to grow. The Uruguayan family-owned company is constantly evaluating new solutions to meet emerging customer needs, such as Mac3 HC easyFIT – a compact and versatile inverter that further expands application possibilities in future projects.
