Product catalog summary

Introduction
The document introduces Juwent's PK floor convector line, designed for efficient heating and cooling in modern spaces with large glazed areas. Established in 1992, Juwent focuses on quality and innovation, offering products that meet various acoustic and efficiency requirements.

PKG Floor Convectors for Heating
PKG convectors are designed for heating public utility premises and living quarters where conventional heaters are unsuitable. They operate in convective heat transfer mode, suitable for locations with strict noise requirements. Key components include a galvanized steel trench, a heat exchanger, and optional decorative frames and grilles. They support heating mediums up to 95°C and a pressure of 0.6 MPa.

Technical Specifications
The document provides detailed technical data, including weight, water capacity, and heating parameters for various models and sizes. Tables show heat power, water flow, and hydraulic resistance under different ambient temperatures and water supply/return conditions.

PKWG and PKWGC Floor Fan Convectors
PKWG models include fans for enhanced efficiency and control, while PKWGC models offer both heating and cooling capabilities with 2- or 4-pipe systems.

Additional Equipment and Control
Additional equipment includes decorative frames and grilles. Automatic equipment and control systems are available for enhanced functionality.

Installation and Selection
Guidelines for connection and installation are provided, along with criteria for selecting the appropriate floor convector model based on specific requirements.

Cooling Parameters of PKwGC-15-34-L-4R Convectors
This section provides detailed specifications for the PKwGC-15-34-L-4R convectors, including fan speeds, ambient temperatures, water parameters, heat power, water flow, and hydraulic resistance.

Correction Coefficients
Correction coefficients are provided for different water and room temperatures, allowing adjustments for parameters other than the standard 75/65/20.

Additional Equipment
This section describes additional equipment available for floor convectors, including grilles, frames, automatic equipment, thermostatic valves, thermal actuators, and power supplies.

Installation and Connection
Guidelines for installation and connection cover positioning, water connection, electrical connection, and making screed, emphasizing compliance with building regulations and standards.

Flow Resistance Factor Charts
Charts illustrate the pressure drop and water flow for different convector models, aiding in the selection and design process.

Selection of Floor Convectors
This section outlines options for floor convectors, including PKG floor convectors for heating and PKWGC floor fan convectors for heating and cooling, highlighting operational modes and features.

Specifications
Fan convector units are equipped with transverse flow fans and EC motors, offering three-step rotational speed adjustment. They are available with heat exchangers in either a 2-pipe or 4-pipe supply system.

Procedures
When selecting fan convector units, a basic speed is chosen from three options, considering sound pressure requirements. Based on the chosen speed, a convector of appropriate length is selected to meet the room's heating and cooling power needs.

Norms and Standards
Sound pressure levels are measured according to VDI 2081 standards. Charts provide quick selection of PKG convectors for both heating and cooling, detailing power at various water and ambient temperatures.

Recommendations
Arrangements can be made with the manufacturer for convector units with step-less fan rotational speed adjustment. Contact information for Juwent Szymański, Nowakowski Sp. J. is provided for further inquiries.

Introduction Heating of modern office areas and living quarters with large glazed areas or of special aesthetic needs, requires application of devices that are able to operate efficiently without interfering with intended interior design of such premises. A perfect example of such devices is the JUWENT’s PK floor convector line. When designing this floor convector line, our intention was to provide a wide choice of solutions to meet their further users’ needs. Depending on requirements, we offer solutions for heating, e.g in locations of special acoustic requirements - silent PKW convectors....

Correction coefficients for PKG convectors for parameters other than 75/65/20 Water temperature [OC] Tsupply * table is developed for coefficient of n=1.46 Design demand for heating power with water parameters (Tsupply/Treturn/ Troom) on supply, return and room temperature 60/50/16, respectively, is 820W. For these temperatures, a correction coefficient of 0.696 can be obtained from the table. Then the design power (820W) is divided by this coefficient (0.696) to obtain heating power (1178W), so that a convector with parameters of 75/65/20 is the choice. Hence the relation that the same convector,...
