Door Heater
Air curtain heater installed at factory, logistics center, and cold storage entrances to block outside cold air and maintain indoor temperature. Gas direct-fired operation reduces operating costs compared to electric air curtains.
Entrances are the points where heating loss and outdoor air ingress are greatest. The NBPKOREA Door Heater is designed to form a hot air barrier matched to entrance geometry and opening frequency, contributing to work environment stability and energy loss reduction.
Applications
Door Heater Operation Flow
Cuts off outdoor air flow through the opening with heated air to reduce indoor environment fluctuation.
Product Features
Key Capabilities
Entrance Protection
Air Barrier
Forms a hot air curtain at door opening zones to reduce outdoor air infiltration.
Heating Output
High Thermal Response
Effective at raising the perceived temperature in entrance zones within a short time.
Installation
Simple Field Setup
Configured to reduce the burden of separate heat source equipment installation.
Custom Design
Opening-Based Sizing
Custom specifications proposed based on opening width, height, and door frequency.
Core Modules
Heating Section
Forms a hot air barrier at the entrance zone using a direct-fired heat source or high-temperature air section.
Discharge Nozzle
Discharge direction and air velocity are adjusted to match the opening geometry, reducing outdoor air ingress.
Control Section
Operates at the required timing by linking door open/close signals, temperature conditions, and manual/auto modes.
Mounting Frame
Manufactured for easy site installation and maintenance, fitting the top or side structure of the entrance.
Selection Criteria
Opening Size
Airflow, discharge velocity, and equipment length are calculated based on entrance width and height.
Opening Frequency
Continuous or intermittent operation mode is reviewed based on door open time and traffic patterns.
Temperature Difference
Required heating capacity is adjusted based on indoor/outdoor temperature difference and seasonal conditions.
Work Environment
Installation position and discharge direction are designed considering noise, perceived airflow, and work traffic.
Specifications
Door heater performance varies significantly depending on opening conditions. We optimize and propose airflow and heating capacity based on entrance size, opening frequency, indoor/outdoor temperature difference, and work traffic patterns.
