HW-RQ-WG004 LPG Fryer Heating Technology and Cold Zone Structure
The HW-RQ-WG004 uses a natural workflow for commercial LPG frying: the combustion system generates heat below the oil tank, while the liquid expansion temperature control system responds to changes in oil temperature. Operators can use the mechanical multi-level knob to adjust heating intensity for different foods and cooking loads. The deep cold zone separates the lower tank area from the main frying zone, allowing food particles to move away from the primary heating tubes. This combination is designed for repeated frying operations where temperature management, oil handling and equipment cleaning are important. The fryer also features a thick stainless steel body, funnel-shaped oil tank, oil drain valve, Min/Max markings, frying basket and basket hanging rod for practical daily commercial use.
The HW-RQ-WG004 is a freestanding commercial LPG gas fryer developed for restaurants, foodservice businesses and professional kitchens requiring larger single-tank frying capacity.
The series provides five capacity options from 20L to 72L, allowing commercial operators to select a suitable fryer according to production volume and kitchen requirements.
One of the key structural features is the deep cold zone design. The lower part of the oil tank provides a deeper area beneath the main frying zone, allowing food particles and frying residue to move away from the primary heating tubes. This design helps reduce direct contact between food debris and the heating area during repeated frying.
The fryer uses a liquid expansion temperature control system together with a sensitive temperature probe. The mechanical multi-level control knob allows operators to adjust heating intensity according to different ingredients and frying requirements.
The thick stainless steel body provides a practical commercial equipment structure, while food-contact components use 304 stainless steel. Customers requiring a higher material specification can request full-machine 304 or 316 stainless steel customization.
The LPG heating system is designed for efficient combustion and rapid heating. Depending on the model, the fryer can use cross heating tubes, while HW-RQ-WG004-B and HW-RQ-WG004-C can also be configured with straight heating tubes.
For daily operation, the funnel-shaped oil tank helps make oil drainage and cleaning more convenient. The perforated divider helps separate food debris from the heating area, while the Min/Max markings provide a clear reference for oil filling.
The standard frying basket and hanging rod make it easier to drain excess oil after frying.

Product FAQs
What is the oil capacity range of the HW-RQ-WG004 series?
The HW-RQ-WG004 series includes five models with oil tank capacities ranging from 20L to 72L. The recommended maximum oil fill ranges from approximately 15L to 66L depending on the model.
What is the purpose of the deep cold zone?
The deep cold zone provides a lower-temperature area beneath the main frying zone. Food particles can move into this lower area, helping reduce direct contact between food debris and the primary heating tubes during frying.
Which models support straight heating tubes?
HW-RQ-WG004-B and HW-RQ-WG004-C can be configured with either cross heating tubes or straight heating tubes. HW-RQ-WG004-A, D and E use the cross heating tube configuration according to the current specifications.
Is the HW-RQ-WG004 suitable for restaurants and high-volume foodservice?
Yes. The series is designed for professional commercial foodservice applications and provides five different tank capacities. Larger models can be selected when higher frying capacity is required. The appropriate model should be selected according to the customer’s menu, cooking volume, kitchen space and LPG system.
Can the HW-RQ-WG004 be customized for OEM and private label projects?
Yes. Shangbang supports OEM and ODM customization including full 304 or 316 stainless steel construction, temperature control, machine structure, rounded corners, knobs, baskets, tank capacity, tank configuration, logo application, packaging and user manuals.
