1. INTRODUCTION
The company PROTON GROUP LLC thanks you for choosing
air heaters PROTON.
This manual is an integral part of the product and must
always accompany it, and should be transferred to the user.
To provide proper wiring and application of the unit, please,
study this manual thoroughly before installation.
We recommend keeping the manual safe in order to address
it during operation.
The user should strictly follow safety instructions while
installing, using and servicing the unit.
The access to the unit must be restricted for unauthorized
and unqualified personnel. The appropriate training of the
maintenance sta should be provided.
The manufacturer disclaims any responsibility for damages
caused by wrong installation and misuse of the unit.
The manufacturer disclaims any responsibility for damages
done by people who didn’t study the manual.
The manufacturer preserves the right to introduce any
amendments to the manual without prior notification.
The manufacturer preserves the right to alter the
construction which doesn’t impact its functioning and basic
technical parameters.
The air heater is intended only and exclusively to be installed
and used for purposes which it has been designed. Any
misuse or noncompliance with the manufacturer’s
instructions may lead to property damages, personnel injuries
or death. The user has to take measures to eliminate
possibilities of misuse of the unit.

2. SAFETY PRECAUTIONS
Before any actions connected with the air heater, please, study
this manual to provide safety.
Installation and connection of the equipment to pipelines and
networks must be performed by qualified personnel only,
having appropriate access.
During installation, start-up, repair and maintenance of the
air heater follow the safety rules.
Install the unit on a firm base or surface, which can stand its
weight filled with water.
Use screws appropriate for the material which the base is
made of.
Check correctness of connections of the system, accordance
of the heat medium parameters to the parameters indicated
on the rating plate as well as leak proof of joints before filling
in the heat medium.
Avoid substances and impurities in the heat medium causing
copper corrosion.
Check compliance of parameters of the electrical supply
network to the ones indicated on the unit’s rating plate
before connecting to the power supply.
Check grounding. Prohibit the use of the unit without
grounding as it may cause property damages, personnel
injuries and death.
Current network which feeds the unit’s motor and controls
must be additionally protected by a fuse to prevent
consequences of shunt fault.
Provide protection of a fan against overheat by connecting
protection devices to contacts of fan temperature sensor.
While the air heater is operating under low temperatures, the
-t
user must provide protection of the water heat exchanger or
use heat medium with special additives preventing copper
corrosion.
To prevent defrosting of the air heater’s heat exchanger
when circulation of the heat medium is stopped during a
heating period under outdoor temperatures lower than 0°C,
you need to drain the heat medium from the heat exchanger
and blow it o by compressed air.

3. GENERAL INFORMATION
Explosion proof
design
PROTON EX
It is designed to heat industrial premises and warehouses under conditions of extra explosion safety.
This equipment is to be mounted in buildings with increased probability of explosion as a result of
interaction with dangerous materials as well as because of some technological processes.
Principle of operation
The air heater PROTON is an element of a
heating system. It is designed for heating air and
Outlet pipe
Inlet pipe
its even distribution in buildings. Its work is
based on axial fan functioning, which charges
the air and pass it through a copper-aluminum
heat exchanger in which the heat medium
(hot water) flows at certain temperature.
Heated air is supplied into a room and is directed
to the working area by directing louvers.
Applications
Chemicals production premises
Paint and varnish industry
Furniture production premises
Oil- and gas processing factories
Workshops with installed vessels and
containers of high pressure
Premises of production of highly explosive
substances
Model range
PROTON EX 30 – heating power 10-30 kW
PROTON EX 50 – heating power 25-50 kW
PROTON EX 70 – heating power 40-70 kW

5. CONSTRUCTION
Major components of the air heater PROTON EX
Casing
Metal casing is made of elements dyed by protection cover that
provides long-time protection against corrosion and conforms with
European quality and design standards.
Fan
Protection-proof axial fan of the air heater PROTON EX provides
even air distribution on heat exchanger’s surface. The construction
and material of the fan prevents sparks and local temperature
increase in motor windings. Overheat protection is provided by a
thermistor sensor, not a temperature sensor as for standard motors.
The motor meets European requirements on explosion safety.
Rated power supply of PROTON EX fans is 3~400 V/50 Hz. Motor
protection rating is IP44 (EN60529), isolation class THCL155,
protection class II2Gc ExeIIB T3. Operating temperature range is
-20 °C to +40 °C.
Heat exchanger
A heat exchanger consists of copper tubes and aluminum lamellas
pressed on them. It is equipped with copper pipes with threading
connection (external thread 3/4”). Copper-aluminum heat exchanger
is distinguished by high eciency, is not exposed to corrosion if you
don’t use substances and impurities in the heat medium causing
copper corrosion. Maximal parameters of heat medium supply are
130 °C/1,6 MPa.
Directing louvers
They are made of steel and dyed by special paint, and provide minimal
air resistance at the outlet from the air heater. Aesthetic look and
high protection from corrosion guarantee durability and safety.

Provide at least one cock for heat medium drainage on the bottom point on the piping scheme of the
air heater.
5.
Provide at least one air outtake on the upper point on the piping scheme of the air heater.
6.
The diameter of pipes should be selected in accordance with hydraulic calculations of the heat supply
system.
7.
Heating tubes from the heating system pipe to the air heater must be installed with the pitch of 3°

9. CONTROL ELEMENTS
ECOMATIC PRO
ECOMATIC PRO is a control element with help of which
advantages of heating and ventilation systems become
more noticeable and perceivable as its use provide
comfortable inside temperature and significant energy
of climatic conditions in a room. Using PROTON PRO you increase equipment lifetime protecting it from
functioning under alarm mode.
STD EX Control board
Control board ECOMATIC STD EX is a board in which automatic switch, a
thermistor relay of motor protection, and a “dry contact” of firefighting device
are mounted. The board protects a motor from alarms, controls temperature of
cable windings. It is a mandatory element for air heaters PROTON EX.
Three-phase construction.
Control over motor temperature.
Protection device against shunt fault.
Connection to «dry contacts» of fireproof main.
DS 2M Сontrol device
The device regulates three-phase motor of a fan by turning on/o from an
external thermostat and regulating rotations through recommutation of
windings according to the scheme “delta” and “star” with help of a manual
switch.
Possibility of smooth star-up (start - basing on “star”, operation - basing on “delta”).
Possibility to regulate a group of air heaters.
Simple and reliable construction.
Dustproof and moisture resistance.
Remote control of turn on/o of motor.
savings due to fast response of the system to changes
RD Programmable thermostat
