Key Features of the HYDROVAR

• No need for additional pressure sensors:

The ESH..H is fitted as standard with a pressure

transmitter.

• No need for special pumps or motors.

• ESH..H is already pre-wired.

• No need for IN LINE filters.

HYDROVAR already includes the THDi filter embedded

as standard.

• No need for bypass or safety systems:

The ESH..H will immediately switch off when demand

drops to zero or when it exceeds maximum pump

capacity; thus making installation of additional safety

devices unnecessary.

• Anti-condensation device:

The HYDROVAR is fitted with anti-condensation

devices which switch on when the pump is in standby

in order to prevent condensation forming in the unit.

Identification code:

ESH..H models are identified by the letter “H” and

“/2”, “/3” or “/4” in the standard identification code

of the e-SH product range.

Example:

ESHSH40-250/110/P25VSS4 /4

H = with integrated HYDROVAR

/4 = HYDROVAR HVL4.110 [3~ 380-460 V (50/60 Hz)].

Background and context

For all pumping needs in commercial or residential building

and in industry applications, the demand for intelligent

pumping systems is constantly growing. Controlled systems

offer many advantages: reduced operating costs for the

lifetime of the pump, lower environmental impact, longer

lifetime of piping systems and networks.

For this reason, Lowara has developed the ESH..H: an

intelligent pumping system which assures high level

performance with energy consumption tailored to the

system’s demand.

Benefits of ESH with HYDROVAR

Saving: ESH..H transforms the ESH pumps into variable

speed intelligent pumping systems. Thanks to the

HYDROVAR, the speed of each pump varies so as to

maintain a constant flow, a constant pressure, or a

differential pressure. In doing so, at any point in time, the

pump only receives the energy required. This in turns allows

for considerable savings, especially for systems that have

varying loads throughout the day.

Easy installation and space-saving: ESH..H saves

time and space during installation. The Hydrovar is delivered

already mounted on the motor (for models up to 22kW).

The hydrovar is kept cool by the motor fan and does not

require a control panel. In order to function, only fuses

on the supply line are needed (Check your local electrical

installation regulations). A wall-mounted HYDROVAR

version is available for higher power outputs (up to 45 kW).

Standard motors: ESH..H models are fitted with three-

phase standard TEFC motors with insulation class 155 (F).
